Grep SED

The grep -il statement finds all instances of Hello in files ending in txt (i = ignore case, , l = only list the filename). The file names are passed to sed, which runs a regular expression to change all instances of Hello to Goodbye. Since sed doesn't overwrite a file, I redirected the output to a temp file and then renamed it back to the original file name.

#!/bin/sh

for file in $(grep -il "Hello" *.txt)
do
sed -e "s/Hello/Goodbye/ig" $file > /tmp/tempfile.tmp
mv /tmp/tempfile.tmp $file
done

Remove ^M characters at end of lines in vi

To remove the ^M characters at the end of all lines in vi, use:

:%s/^V^M//g

The ^v is a CONTROL-V character and ^m is a CONTROL-M. When you type this, it will look like this:

:%s/^M//g

In UNIX, you can escape a control character by preceeding it with a CONTROL-V. The :%s is a basic search and replace command in vi. It tells vi to replace the regular expression between the first and second slashes (^M) with the text between the second and third slashes (nothing in this case). The g at the end directs vi to search and replace globally (all occurrences).
