I've written a template engine script that uses cut to extract certain elements from a file, but I want to use grep in place of the cut. Here is the code I have written:
#!/bin/bash
IFS=@ #makes @ a delimiter.
while read line
do
dataspace=`echo ${line} | cut -d'=' -f1`
value=`echo ${line} | cut -d"=" -f2`
printf -v $dataspace "$value" #make the value stored in value into the name of a dataspace.
done < 'template.vars' #read template.vars for standard input.
skipflag=false #initialize the skipflag to false
while read line #while it is reading standard input one line at a time
Just came to the conclusion that the code blocks system here does not support bash. Anyway, since stackoverflow isn't letting me put Bash into codeblocks, I am not putting the entire script since it would look nasty. Based on what is currently high-lighted, how would I go about changing the part using the cut command into a line using the grep command?
As has been noted, you should give more information for a better answer. Going with what you have, I would say that awk is a better option than grep
dataspace=$(awk '$0=$1' FS== <<< "$line")
value=$(awk '$0=$2' FS== <<< "$line")
