Read lines in a text file with bash
In bash it’s very easy to read a text file line by line and do something to each line. I do this in cygwin a lot to parse logs and other large files.
Your input file needs to have unix-style line endings or bash will get very confused. This trips me up a lot when working on files created with a Windows program.
There are many other ways of doing for/next loops in bash, but this is simple, fast and easy for quick scripts.
#! /bin/bash
while read line
do
echo $line
done < your_file.txt
