It's not clear what all the possible reasons for an alert could be, but the following works for your sample:
perl -ne 'undef $err, print "$1 ..." if /^={21}([^=]+)={24}/;
$err = 1 if /ERROR/;
print $err ? "Alert" : "Ok!", "\n" if /={45}/'

I have created a bash script that runs on several machines that contain different git local repositories. It tests many conditions and tells me if the repository has uncommitted files, untracked files, and one test in particular tells me that the local is ahead or behind the remote by the number of commits. The problem with the script is that it doesn't return or set an 'ok' flag which I use to echo the "ok" message if everything is in sync. So, I get the message that it's ahead or behind, but then get the "ok" message. Here is the portion of the script that does the ahead or behind, and I can't see how to get it to set an ok = false somehow.
git fetch>/dev/null && git branch -v |
perl -wlne'
print "$ENV{reponame} [$1] --> $3 $2"
if /^..(\S+)\s+([a-f0-9]+)\s+(\[(?:ahead|behind)\s+\d+\])/
' |
while IFS= read -r MOD; do
ok=false
printf ' %s\n' "$MOD" # Replace with code that uses $MOD
done
if $ok; then
echo " OK --> $reponame [$br] $rev"
fi
I copied this from another script and don't really understand the IFS = read -r MOD; section that I thought might set the flag, but it doesn't occur.
This is the output I get:
bin [develop] --> [behind 1] 026e1ad
OK --> bin [develop] 026e1ad
OK --> notes [develop] 4cd077f
OK --> indecks [develop] e6b4293
OK --> queue [develop] 5469679
OK --> frameworks [master] 05fedb6
OK --> dashboard [isolate] f8b1101
OK --> nodejs [develop] 5af2ea7
OK --> perl-forth [master] 45cc837
OK --> blog [master] c19edfd
Note that for bin I get:
bin [develop] --> [behind 1] 026e1ad
OK --> bin [develop] 026e1ad
I'd rather not get that OK after the behind 1! Another script checks for any non-OK in the left column and sends me an email.
With the perl and all the piping, how could I set the ok variable before it prints?
In most shell implementations, all processes in a pipeline are run in a subshell. In this case, you're running a while loop at the end of a pipeline, so it (and it alone) is in the subshell. Whether you set ok to false or not, it has no effect on the if block because that's run the main shell, which doesn't inherit variables from the subshell.
zsh and AT&T ksh (but not other ksh implementations) execute the last command in the main shell and not a subshell. POSIX permits either behavior, but the bash behavior is far more common among shells.
The easiest way to handle this is to run the entire command you're interested in in a subshell:
git fetch>/dev/null && git branch -v |
perl -wlne'
print "$ENV{reponame} [$1] --> $3 $2"
if /^..(\S+)\s+([a-f0-9]+)\s+(\[(?:ahead|behind)\s+\d+\])/
' |
(while IFS= read -r MOD; do
ok=false
printf ' %s\n' "$MOD" # Replace with code that uses $MOD
done
if $ok; then
echo " OK --> $reponame [$br] $rev"
fi)
This puts both parts using the ok variable in the same subshell, so you can modify it and it will have an effect.

I have a file that is just outside of this directory that I need to copy to all of the files that end with "_1.src" inside the directory.
I'm working with unix in the Terminal app, so I tried writing this for loop, but it rejected my regular expression:
for .*1.src in ./
> do
> cp ../1.src
> done
I've only written regular expressions in Python before and have minimal experience, but I was under the impression that .* would match any combination of characters. However, I got the following error message:
-bash: `.*1.src': not a valid identifier
I then tried the same for loop with the following regular expression:
^[a-zA-Z0-9_]*1.src$
But I got the same error message:
-bash: `^[a-zA-Z0-9_]*1.src$': not a valid identifier
I tried the same regular expression with and without quotation marks, but it always gives the same 'not a valid identifier' error message.
Tested on Bash 4.4.12, the following is possible:
$ for i in ./*_1.src; do echo "$i" ; done
This will echo every file ending with _1.src to the screen, thus moving it will be possible as well.
$ mkdir tmp
$ for i in ./*_1.src; do mv "$i" tmp/.; done
I've tested with the following data:
$ touch P{1,2}{0,1,2}_{0..6}.{src,tgt,atag}
$ ls

Apparently, my previous answer didn't work. But this seems to:
$ for x in `echo ./P[01][012]_1.src`; do echo "$x"; done
./P01_1.src
./P02_1.src
So, when you run this echo alone, this pattern gets expanded into many names:
$ echo ./P[01][012]_1.src # note that the 'regex' is not enclosed in quotes
./P01_1.src ./P02_1.src
And then you can iterate over these names in a loop.
BTW, as noted in the comments, you don't even need that echo, so you can plug the pattern right into the loop:
for x in ./P[01][012]_1.src; do echo "$x"; done
Please correct me if your goal is something other than
"overwrite many existing files sharing a common suffix with the contents of a single file"
find /path/to/dest_dir -type f -name "*_1.src" |xargs -n1 cp /path/to/source_file
Note that without the -maxdepth 1 option, find will recurse through your destination directory.
Thanks to everyone; this is what ended up working:
for x in `echo ./P[0-9]*_1.src`
> do
> cp ../1.src "$x"
> done
This loop allowed me to copy the contents of the one file to all of the files in the subdirectory that ended with "_1.src"
I have a real simple script to update a table based on a flat file but am concerend as the list keeps getting longer and longer a non valid formatted variable will get introduced and cause issues.
#!/bin/bash
OLDIFS=$IFS
IFS=,
file1=file.csv
while read mac loc; do
dbaccess modemdb <<EndOfUpdate 2>/dev/null
UPDATE profile
SET localization= '$loc'
WHERE mac_address = '$mac';
EndOfUpdate
done <"$file1"
IFS=$OLDIFS
The file contents are as such.
12:BF:20:1B:D3:22,RED-1234
12:BF:20:2D:FF:1B,BLUE-1234
12:BF:20:ED:74:0D,RED-9901
12:BF:20:02:69:7C,GREEN-4321
12:BF:20:02:6B:42,BROWN
12:BF:20:ED:74:0D,BLACK
What I am having difficulty with is how can I set a format check of the $mac and $loc variables so if they don't match it stops running. the $loc can be any 19 digits so just need to make sure its not null and not longer. The mac address needs to be not null and in the format as in the file. I found reference in another post to this check but not sure how to integrate.
`[[ "$MAC_ADDRESS" =~ "^([0-9a-fA-F]{2}:){5}[0-9a-fA-F]{2}$" ]]`
Looking for help on how to create the validations.
Thanks,
Check MAC address with regex:
#!/bin/bash
file1=file.csv
while IFS="," read mac loc; do
if [[ "$mac" =~ ^([0-9a-fA-F]{2}:){5}[0-9a-fA-F]{2}$ ]]; then
dbaccess modemdb <<EndOfUpdate 2>/dev/null
UPDATE profile
SET localization= '$loc'
WHERE mac_address = '$mac';
EndOfUpdate
else
echo "Error: $mac"
fi
done <"$file1"
Your regex is for bash only a string if you use quotation marks.
I am actually using wamp 2.5 with PHP 5.5.12 and when I try to create a phar file it returns me the following message :
Uncaught exception 'UnexpectedValueException' with message 'creating archive "..." disabled by the php.ini setting phar.readonly'
even if I turn to off the phar.readonly option in php.ini.
So how can I enable the creation of phar files ?
I had this same problem and pieced together from info on this thread, here's what I did in over-simplified explanation:
in my PHP code that's generating this error, I added echo phpinfo(); (which displays a large table with all sort of PHP info) and in the first few rows verify the path of the php.ini file to make sure you're editing the correct php.ini.
locate on the phpinfo() table where it says phar.readonly and note that it is On.
open the php.ini file from step 1 and search for phar.readonly. Mine is on line 995 and reads ;phar.readonly = On
Change this line to phar.readonly = Off. Be sure that there is no semi-colon at the beginning of the line.
Restart your server
Confirm that you're phar project is now working as expected, and/or search on the phpinfo()table again to see that the phar.readonly setting has changed.
phar.readonly can only be disabled in php.ini due to security reasons.
If you want to check that it's is really not done using other method than php.ini then in terminal type this:-
$ php -r "ini_set('phar.readonly',0);print(ini_get('phar.readonly'));"
If it will give you 1 means phar.readonly is On.
More on phar.configuration
Need to disable in php.ini file
Type which php
Gives a different output depending on machine e.g.
/c/Apps/php/php-7.2.11/php
Then open the path given not the php file.
E.g. /c/Apps/php/php-7.2.11
Edit the php.ini file
could do
vi C:\Apps\php\php-7.2.11\php.ini
code C:\Apps\php\php-7.2.11\php.ini
[Phar]
; http://php.net/phar.readonly
phar.readonly = Off
; http://php.net/phar.require-hash
phar.require_hash = Off
Save
Using php-cli and a hashbang, we can set it on the fly without messing with the ini file.
testphar.php
#!/usr/bin/php -d phar.readonly=0
<?php
print(ini_get('phar.readonly')); // Must return 0

For anyone who has changed the php.ini file, but just doesn't see any changes. Try to use the CLI version of the file. For me, it was in /etc/php/7.4/cli/php.ini
Quick Solution!
Check:
cat /etc/php/7.4/apache2/php.ini | grep phar.readonly
Fix:
sed -i 's/;phar.readonly = On/;phar.readonly = Off/g' /etc/php/7.4/apache2/php.ini
Friends , im trying to automate a routing using expect , basically its a debug plugin in a special equipment that i need to log some data , to access this debug plugin my company needs to give me a responsekey based on a challengekey , its a lot of hosts and i need to deliver this by friday , what i've done so far.
#!/usr/bin/expect -f
match_max 10000
set f [open "cimc.txt"]
set hosts [split [read $f] "\n"]
close $f
foreach host $hosts {
spawn ssh ucs-local\\marcos#10.2.8.2
expect "Password: "
send "Temp1234\r"
expect "# "
send "connect cimc $host\r"
expect "# "
send "load debug plugin\r"
expect "ResponseKey#>"
sleep 2
set buffer $expect_out(buffer)
set fid [open output.txt w]
puts $fid $buffer
close $fid
sleep 10
spawn ./find-chag.sh
sleep 2
set b [open "key.txt"]
set challenge [read $b]
close $b
spawn ./find-rep.sh $challenge
sleep 3
set c [open "rep.txt"]
set response [read $c]
close $c
puts Response-IS
send "\r"
expect "ResponseKey#> "
send "$response"
}
$ cat find-chag.sh
cat output.txt | awk 'match($0,"ChallengeKey"){print substr($0,RSTART+15,38)}' > key.txt
$ cat find-rep.sh
curl bla-blabla.com/CIMC-key/generate?key=$1 | grep ResponseAuth | awk 'match($0,"</td><td>"){print substr($0,RSTART+9,35)}' > rep.txt
i dont know how to work with regexp on expect so i put the buffer output to a file and used bash script , the problem is that after i run the scripts with spawn looks like my ssh session is lost , does anyone have any tips? should i use something else instead of spawn to invoke my scripts?
expect -re "my tcl compatible regular expression goes here"
Should allow you to use regular expressions.
