use sed replace ""string"\1\"787" to "string"\1\"787" in cygwin - regex

I am trying to search string and replace string in a file. I used the below code:
sed -e 's/{"AP_SESSION_ID"\1\"787"}/{"AP_SESSION_ID"\1\"800"}/g' FILE|tee FILE
but it is not working and the output is like this:
sed: number in \[0-9] invalid
My environment is CYGWIN.
sample file is:
DP_SESSION_ID is a sting for values
DP_SESSION_ID is aplicat
"DP_S42SETTACC_TYPE"\1\"02"
"DP_SAP_CLIENT"\1\"460"
"DP_SAP_COMM_CONNECTION"\1\"JAVA_COMM_TOOL_ANALYZER"
"DP_SAP_CONNECTION"\1\"JAVA_TOOL_ANALYZER"
"DP_SAP_TOOLBI_CONNECTION"\1\"JAVA_TOOLBI_ANALYZER"
"DP_SESSION_ID"\1\"808"
I want search this "DP_SESSION_ID"\1\" sting and replace corresponding number like 808 in file prenatally(windows env), and i wand sing line command in windows bat command or perl command i don't want scrip or program
even i have installed cygwin tool in my server so unix also ok but single line command
server: windows 2008,cygwin x
using tool : datastage server jobs
perl -pi -e 's{" "DP_SESSION_ID"\1\"808 '"}{' "DP_SESSION_ID"\1\"900 '"'"}g' " file name
this code is not working
Please give good solution

You need to "escape" the backslashes by using two in a row:
sed -e 's/{"AP_SESSION_ID"\\1\\"787"}/{"AP_SESSION_ID"\\1\\"800"}/g' FILE|tee FILE
Otherwise the \1 is treated as a backreference, and you have no subgroups (parenthesized expressions) to reference.

Apart from back-slashes, IMO you also need to escape the quotes.
sed -e 's/{\"AP_SESSION_ID\"\\1\\\"787\"}/{\"AP_SESSION_ID\"\\1\\\"800\"}/g' FILE|tee FILE

Unable to use sed command in Windows Command Prompt due to 'unterminated address regex'

I'm trying to run a sed command on a Windows machine from the command prompt (CMD.exe) but I am struggling to understand the regular expression and how to escape the string properly when running on Windows. Ideally, I want to develop a solution that works across UNIX and Windows.
sed is not available on Windows so I have installed it via the gnuWin32 project which works well.
The unix format for the command is:
sed -i '' -e 's/\\/_next/\\.\\/next/g' out/**.html
Through a process of trial an error I have managed to get this far:
sed -i \'\' -e \'s/\\/_next/\\.\\/next/g\' out/**.html
but I get an error:
sed: -e expression #1, char 27: unterminated address regex
So there's definitely something wrong with my regex, probably the escaping of various parts?
Any ideas how I might go about fixing this?
Update:
I'm getting the code from here where unfortunately only Linux and OSX are covered.
You need to use
sed -i "s/\\/_next/\\.\\/next/g" out/**.html
The Windows GNU sed does not require the '' empty argument after -i option, they can be safely removed.
Also, the sed command in Windows console should be used in double quotes.

Bash on macOS: How replace a path in a file with another string?

For integration tests, I have output that contains full file paths. I want to have my test script replace the user-specific start of the file path (e.g. /Users/uli/) with a generic word (USER_DIR) so that I can compare the files.
The problem, of course, are the slashes in the path. I tried the solutions given here and here, but they don't work for me:
#!/bin/bash
old_path="/Users/uli/"
new_path="USERDIR"
sed -i "s#$old_path#$new_path#g" /Users/uli/Desktop/replacetarget.txt
I get the error
sed: 1: "/Users/uli/Desktop/repl ...": invalid command code u
This is the version of sed that comes with macOS 10.14.6 (it has no --version option and is installed in /usr/bin/, so no idea what exact version).
Update:
I also tried
#!/bin/bash
old_path="/Users/uli/"
old_path=${old_path//\//\\\/}
new_path="USERDIR"
regex="s/$old_path/$new_path/g"
echo $old_path
echo $regex
sed -i $regex /Users/uli/Desktop/replacetarget.txt
But I get the same error. What am I doing wrong?
BSD sed requires an argument following -i (the empty string '' indicates no backup, similar to argumentless -i in GNU sed). As a result, your script is being treated as the backup-file extention, and your input file as the script.
old_path="/Users/uli/"
new_path="USERDIR"
sed -i '' "s#$old_path#$new_path#g" /Users/uli/Desktop/replacetarget.txt
However, sed is a stream editor, based on the file editor ed, so using -i is an indication you are using the wrong tool to begin with. Just use ed.
old_path="/Users/uli/"
new_path="USERDIR"
printf 's#%s#%s#g\nwq\n' "$old_path" "$new_path" | ed /Users/uli/Desktop/replacetarget.txt
Obligatory warning: neither editor is parameterized as such; you are simpling generating the script dynamically, which means it's your responsibility to ensure that the resulting script is valid. (For example, if either parameter contains a ;, it had better be escaped to prevent (s)ed from seeing it as a command separator.)

Linux console perl replace not working on large file

On ubuntu I'm running a console perl replace on a csv file of ~500MB. This is the call:
perl -i -pe 's/AS100\n/AS100/g' test.csv
Before run it on the complete file, I extracted a subset of it of ~30MB and run this script successfully.
When running on the full file, no substitution is done, and no error or message is showed.
I've tried also with sed, but the behavior is the same.
How can I solve this issue?
Thank you
If you have room, try to do this instead to look at the substitution as it is done to another file:
perl -pe 's/AS100\n/AS100/g' test.csv | tee > test2.csv
My question is though, is it only the rows ending with AS100 that needs the newline removal?
After trying everything, I found out that in the original file the pattern was:
As100\r
and that the \n was a conversion done by Sublime Text when saving the test file.
So the correct code to do the trick was:
perl -i -pe 's/AS100\r/AS100/g' test.csv

SED command matches regex but does not substitute

I am working on building a .sed file to start scripting the setup of multiple apache servers. I am trying to get sed to match the default webmaster email addresses in the .conf file which works great with this egrep. However when I use sed to try and so a substitute search and replace i get no errors back but it also does not do any substituting. I test this by running the same egrep command again.
egrep -o '\b[A-Za-z0-9._%-]+#[A-Za-z0-9.-]+(\.[A-Za-z]{2,4})?\b' /home/test/httpd.conf
returns
admin#your-domain.com
root#localhost
webmaster#dummy-host.example.com
The sed command I'm trying to use is
sed -i '/ServerAdmin/ s/\b[A-Za-z0-9._%-]+#[A-Za-z0-9.-]+(\.[A-Za-z]{2,4})?\b/MY_ADMIN_ADDRESS#gmail.com/g' /home/test/httpd.conf
After running I try and verify the results by running the egrep again and it returns the same 3 email address indicating nothing was replaced.
Don't assume that any two tools use the same regular expression syntax. If you're going to be doing replacements with sed, use sed to test - not egrep. It's easy to use sed as if it were a grep command: sed -ne '/pattern/p'.
sed must be told that it needs to use extended regular expressions using the -r option then making the sed command as follows.
sed -ir '/ServerAdmin/ s/\b[A-Za-z0-9._%-]+#[A-Za-z0-9.-]+(\.[A-Za-z]{2,4})?\b/MY_ADMIN_ADDRESS#gmail.com/g' /home/test/httpd.conf
Much thanks to Kent for pointing out that the address it was missing wasnt following a ServerName

How to go from a multiple line sed command in command line to single line in script

I have sed running with the following argument fine if I copy and paste this into an open shell:
cat test.txt | sed '/[,0-9]\{0,\}[0-9]\{1,\}[acd][0-9]\{1,\}[,0-9]\{0,\}/{N
s/[,0-9]\{0,\}[0-9]\{1,\}[acd][0-9]\{1,\}[,0-9]\{0,\}\n\-\-\-//}'
The problem is that when I try to move this into a KornShell (ksh) script, the ksh throws errors because of what I think is that new line character. Can anyone give me a hand with this? FYI: the regular expression is supposed to be a multiple line replacement.
Thank you!
This: \{0,\} can be replaced by this: *
This: \{1,\} can be replaced by this: \+
It's not necessary to escape hyphens.
The newline can be replaced by -e (or by a semicolon)
The cat can be replaced by using the filename as an argument to sed
The result:
sed -e '/[,0-9]*[0-9]\+[acd][0-9]\+[,0-9]*/{N' -e 's/[,0-9]*[0-9]\+[acd][0-9]\+[,0-9]*\n---//}' test.txt
or
sed '/[,0-9]*[0-9]\+[acd][0-9]\+[,0-9]*/{N;s/[,0-9]*[0-9]\+[acd][0-9]\+[,0-9]*\n---//}' test.txt
(untested)
can you try to put your regex in a file and call sed with the option -f ?
cat test.txt | sed -f file.sed
Can you try to replace the new line character with `echo -e \\r`
The Korn Shell - unlike the C Shell - has no problem with newlines in strings. The newline is very unlikely to be your problem, therefore. The same comments apply to Bourne and POSIX shells, and to Bash. I've copied your example and run it on Linux under both Bash and Korn shell without any problem.
If you use C Shell for your work, are you sure you're running 'ksh ./script' and not './script'?
Otherwise, there is some other problem - an unbalanced quote somewhere, perhaps.
Check out the '-v' and '-n' options as well as the '-x' option to the Korn Shell. That may tell you more about where the problem is.
