Top Forums Shell Programming and Scripting Unable to store "python --version" to a shell variable Post 302903236 by vbe on Monday 26th of May 2014 09:39:16 AM

Ok what shell are you using, because so far not knowing I cant reply because of its behaviour: In shells I use (sh ksh...) your variable affectation would not work, and so you would not have any output for your ls part either

this is what I would have written:
Code:
python_version=$(python --version)
echo "****"
echo $python_version
echo "****"
ls_output=$(ls -l python*)
echo "****"
echo $ls_output
echo "****"

PYTHON-CONFIG(1)					      General Commands Manual						  PYTHON-CONFIG(1)

NAME
python-config - output build options for python C/C++ extensions or embedding SYNOPSIS
python-config [ --prefix ] [ --exec-prefix ] [ --includes ] [ --libs ] [ --cflags ] [ --ldflags ] [ --extension-suffix ] [ --configdir ] [ --help ] DESCRIPTION
python-config helps compiling and linking programs, which embed the Python interpreter, or extension modules that can be loaded dynamically (at run time) into the interpreter. OPTIONS
--cflags print the C compiler flags. --ldflags print the flags that should be passed to the linker. --includes similar to --cflags but only with -I options (path to python header files). --libs similar to --ldflags but only with -l options (used libraries). --prefix prints the prefix (base directory) under which python can be found. --exec-prefix print the prefix used for executable program directories (such as bin, sbin, etc). --extension-suffix print suffix used for extension modules (including the _d modified for debug builds). --configdir prints the path to the configuration directory under which the Makefile, etc. can be found). --help print the usage message. EXAMPLES
To build the singe-file c program prog against the python library, use gcc $(python-config --cflags --ldflags) progr.cpp -o progr.cpp The same in a makefile: CFLAGS+=$(shell python-config --cflags) LDFLAGS+=$(shell python-config --ldflags) all: progr To build a dynamically loadable python module, use gcc $(python-config --cflags --ldflags) -shared -fPIC progr.cpp -o progr.so SEE ALSO
