I just stumbled upon a difference between using awk on the commandline and using it in a shellscript.
I have a variable, e.g.: PROG=vim
then i want to check if the package with this name is installed: TEMPVAL=$(dpkg -l | awk '{ if ($2 == "$PROG") print $2 }') (Im using Tempval later in an condition to check if it is installed)
Running this on the commandline works fine. In the shellscript TEMPVAL is always empty.
btw "toinstall" just contains some package names to be installed and comments prefixed with #
full script:
Code:
#!/bin/bash
for prog in `cat toinstall | grep -vP "^#" | grep -vP "^$"`
do
TEMPVAL=$(`dpkg -l | awk '{ if ($2 == "${prog}") print $2}'`)
if [ "$TEMPVAL" == "" ]
then
sudo apt-get install -y $prog
fi
done
bash -x output:
Code:
+ for prog in '`cat toinstall | grep -vP "^#" | grep -vP "^$"`'
+++ dpkg -l
+++ awk '{ if ($2 == "${prog}") print $2}'
+ TEMPVAL=
+ '[' '' == '' ']'
+ sudo apt-get install -y vim
Whats the Problem? I already tried playing with the quotation, but nothing worked. Hope somebody can help me. I'd also appreciate hints or tips if theres a more convenient way of doing what i want to do
