--color=always flag to be tremendously useful. However, grep only prints lines with matches (unless you ask for context lines). Given that each line it prints has a match, the highlighting doesn't add as much capability as it could.
I'd really like to
cat a file and see the entire file with the pattern matches highlighted.
Is there some way I can tell grep to print every line being read regardless of whether there's a match? I know I could write a script to run grep on every line of a file, but I was curious whether this was possible with standard
Here are some ways to do it:
grep --color -E 'pattern|$' file grep --color 'pattern\|$' file egrep --color 'pattern|$' file
Here's something along the same lines. Chances are, you'll be using less anyway, so try this:
less -p pattern file
It will highlight the pattern and jump to the first occurrence of it in the file.
