Re: [PLUG] shell scripting help

Your script has a few issues, but the biggest is that you seem to be confusing bash and php. $ is not a variable indicator in bash, its an expansion operator. This means that your read $i line gets expanded to read "", since i is unset at the beginning of the script.

Have you tried setting it so you give the file name as an argument when you run the script? ./Script FILENAME

I am trying to write a shell script to automate the formatting of a text file in a certain way that is useful to me. the complicated egrep while not ideal does the job when run alone, where $i is the name of the file I want to grep, but when I try put it together in an easy to run script it doesn't do anything. Can someone please point me in the right direction? Thank you.

#!/bin/bash
echo "What is the filename you want to grep?";
read $i;
OUTPUT="$(egrep '\b[A-Z]+| [0-9:]+ \b' $i | grep -v anaged | grep -v No| sort -u | grep -v Na | grep -v Ser | grep -v Ty | grep -v Contact)";
echo "${OUTPUT}";
done
