we have a C++ project in which we need to redirect the standard output to a text file using the following script:
#!/bin/bash
echo "Descend into 'workdirectory' directory"
cd workdirectory
#
for item in *
do
echo " "
echo "EXECUTING" $item
cd $item
Aprog >zoutput02.txt
cd ..
echo "EXECUTION COMPLETE"
done
echo "Return from 'testdirectory' directory"
cd ..
echo " "
When I try to run this script using bash ./scriptname.txt, it returns:
EXECUTING work
./scriptname.txt: line 10: Aprog: command not found
EXECUTION COMPLETE
Return from 'workdirectory' directory
What does this error mean?
Thanks!
You are CD ing around. Aprog is almost certainly not on your path.
Either add Aprog to your PATH or define it in the script.
aprog=/path/to/aprog
$aprog > zoutput02.txt

I would like to automatically format the code when I do commit using rustfmt the same way as I did it before for clang-format -i. I.e. format only the lines of code which has been updated in the commit without touching other code. How to do it?
It might be done using git pre-commit hook in the following way:
Add file pre-commit to the folder .githooks in your repo with the following text:
#!/bin/bash
exe=$(which rustfmt)
if [ -n "$exe" ]
then
# field separator to the new line
IFS=$'\n'
for line in $(git status -s)
do
# if added or modified
if [[ $line == A* || $line == M* ]]
then
# check file extension
if [[ $line == *.rs ]]
then
# format file
rustfmt $(pwd)/${line:3}
# add changes
git add $(pwd)/${line:3}
fi
fi
done
else
echo "rustfmt was not found"
fi
Run in your repo folder:
chmod +x .githooks/pre-commit
git config core.hooksPath .githooks
To make it work for clang-format you need to replace rustfmt with clang-format -i and do corresponding modifications in the check for file extension (cpp\h\hpp\etc).
There are few problems that need to solve.
first there is an error. -bash: /Users/jay/.bash_profile: line 7: `fi'
second, i am having trouble updating .bash_profile to install opencv.
http://www.pyimagesearch.com/2015/06/15/install-opencv-3-0-and-python-2-7-on-osx/
Here are the code below and please help.
many thanks!
# added by Anaconda2 4.2.0 installer
export PATH="/Users/jay/anaconda2/bin:$PATH"
export PATH=/usr/local/bin:$PATH
source '/Users/jay/Downloads/google-cloud-sdk/path.bash.inc'

# The next line updates PATH for the Google Cloud SDK.
if [ -f /Users/jay/Downloads/google-cloud-sdk/path.bash.inc ]; then
source '/Users/jay/Downloads/google-cloud-sdk/path.bash.inc'
fi
# The next line enables shell command completion for gcloud.
if [ -f /Users/jay/Downloads/google-cloud-sdk/completion.bash.inc ]; then
source '/Users/jay/Downloads/google-cloud-sdk/completion.bash.inc'
you have fi statements without if (fi is the 'closing' statement for an 'opening' if):
source '/Users/jay/Downloads/google-cloud-sdk/path.bash.inc'
fi
source '/Users/jay/Downloads/google-cloud-sdk/completion.bash.inc'
fi
bash syntax for if statements is e.g.
if [ -f /var/log/messages ]; then
echo "/var/log/messages exists."
fi
so for you this may be:
if [ -f '/Users/jay/Downloads/google-cloud-sdk/path.bash.inc']; then
source '/Users/jay/Downloads/google-cloud-sdk/path.bash.inc'
fi
and similar for the next line.
and there is a final fi missing at the end of your file.
My specific problem is not the fact that source /venv/bin/activate is being executed everytime I change to a sub folder. The problem is everytime I do it prints "will run" /path/to/.env
I installed autoenv through homebrew in version 0.2.0. This is my .env file:
if [ -z "$VIRTUAL_ENV" ]; then
CUR_DIR=$(pwd)
# search for the next .env
while [[ "$PWD" != "/" && "$PWD" != "$home" ]]; do
env_file="$PWD/.env"
if [[ -f "$env_file" ]]; then
BASE_DIR=$(dirname $env_file)
break
fi
builtin cd ..
done
if [ ! -z "$BASE_DIR" ]; then
echo "Activating that virtualenv"
source ${BASE_DIR}/venv/bin/activate
fi
cd $CUR_DIR
fi
The output in the terminal is something like:
MacBook-Pro:~ llamasramirez$ cd Desktop/oficios/
Will run /Users/llamas/Desktop/oficios/.env
Activating that virtualenv
Will run /Users/llamas/Desktop/oficios/.env
(venv) MacBook-Pro:oficios llamasramirez$ cd django_sites/polls/
Will run /Users/llamas/Desktop/oficios/.env
(venv) MacBook-Pro:polls llamasramirez$
Turns out the problem wasn't in the .env file. The problem was at the activate.sh file.
Opening the autoenv_init function there's a for loop that makes the annoying echo instruction:
for _file in ${_orderedfiles}; do
echo "Will run ${_file}"
autoenv_check_authz_and_run "${_file}"
done
When I comment this the echo doesn't pops up again.
I'm trying to write a program that will allow easier management of Arduino projects. So I wrote bash script that creates all the necessary folders and files for me and when I execute it I runs like champ. Because I want to change directory in the working terminal inside the script I run script like this
. ./initialize.sh
This is also working great, but because I am writing C++ program, sourcing this script from program is giving me headache.
So inside a program I run this script like this:
system(". /usr/lib/avrduino/script/initialize.sh");
and then when I run the program I get this error:
sh: 25: /usr/lib/avrduino/script/initialize.sh: Syntax error: "(" unexpected (expecting "}")
Running the script from the program like this:
system("/usr/lib/avrduino/script/initialize.sh");
works without error but it runs in subshell.
Syntax error points to this line in script
options=("uno" "mega" "mega2560" "atmega8" "atmega168" "atmega328" "pro" "pro5v" "pro328" "pro5v328")
How come that when I run this script outside of the program it's working like champ, but run this script from program and you have a problem ?

. doesn't execute the script as a process, it only loads it into your current shell process.
In that context, your "shebang" line, #!/bin/bash, is just a comment.
(You can put #! doodle poodle noodle there and it will run just as well.)
When you use system, it executes in /bin/sh, and thus your bash script has syntax errors.
One way to execute scripts is to make them executable:
chmod +x /usr/lib/avrduino/script/initialize.sh
and then you can just pass it directly to system:
system("/usr/lib/avrduino/script/initialize.sh");
Or, you could explictly execute it in bash:
system("/bin/bash /usr/lib/avrduino/script/initialize.sh");
OK, here's a way one might solve your "changing directory" problem:
Rewrite initialize.sh so it takes the project name as an argument instead of asking for it interactively (that's how normal Unix tools work, so stick with it).
Then add the following to your .bashrc:
make_project()
{
/usr/lib/avrduino/script/initialize.sh "$1" && cd "$1"
}
Then you can say make_project foo and get transported to the directory "foo".
Most likely it is the misplaced shebang causing a default shell to be run - make sure the shebang is at the beginning of the first line
#!/bin/bash
# rest of script
If that does not work change your system call to
system("/bin/bash /usr/lib/avrduino/script/initialize.sh");
I am attempting to build the ACE library for Mingw GCC 64 bit on Windows. The instructions here state the following:
Install the MinGW tools (including the MinGW Development toolkit) into a common directory, say c:/mingw.
Install the MSYS tools into a common directory, say c:/msys.
Open a MSYS shell. Set your PATH environment variable so your MinGW's bin directory is first:
% export PATH=/c/mingw/bin:$PATH
Add an ACE_ROOT environment variable pointing to the root of your ACE wrappers source tree:
% export ACE_ROOT=/c/work/mingw/ACE_wrappers
From now on, we will refer to the root directory of the ACE source tree as $ACE_ROOT.
Create a file called config.h in the $ACE_ROOT/ace directory that contains:
#include "ace/config-win32.h"
Create a file called platform_macros.GNU in the $ACE_ROOT/include/makeinclude directory containing:
include $(ACE_ROOT)/include/makeinclude/platform_mingw32.GNU
In the above text, don't replace $(ACE_ROOT) with the actual directory, GNU make will take the value from the environment variable you defined previously.
If you lack Winsock 2, add the line
winsock2 = 0
before the previous one.
If you want to install ACE (using "make install") and want all the .pc files generated, set the installation prefix in platform_macros.GNU.
INSTALL_PREFIX=/c/ACE
Headers will be installed to $INSTALL_PREFIX/include, documentation and build system files to $INSTALL_PREFIX/share and libraries to $INSTALL_PREFIX/lib. With INSTALL_PREFIX set, RPATH will be enabled. To disable RPATH (for example, if $INSTALL_PREFIX/$INSTALL_LIB is already a system-known location for shared libraries), set the make macro install_rpath to 0 by adding install_rpath=0 to platform_macros.GNU.
Issue here:
In the MSYS shell, change to the $ACE_ROOT/ace directory and run make:
% cd $ACE_ROOT/ace
% make
Now I noticed that there is no MakeFile in ACE_ROOT/ace which is C:\mingw64\Other\ACE_wrappers\ace
I downloaded my ACE stuff from here.
Any suggestions on what I might be doing wrong ? did I download something wrong ?
You seem to have downloaded the source only distribution, please download the full package, that includes also the GNU makefiles, see http://download.dre.vanderbilt.edu/
ACE comes in the full version with GNUmakefile-s,
In MSYS you give make -f GNUmakefile
EDIT 1
Though building 64-bit binaries is supported for numerous platforms and compilers, the ACE team did not provide it for MINGW. There is something to do ...
EDIT 2
Following script should do the configuration for 64-bit binaries in MingW-64
