On Linux, how to cat a file excluding lines starting with a given string?
On Linux, you can output file content excluding lines starting with a given string with the
grep command with option
grep -v '^string_to_exclude' file.txt
grepis a linux command that print lines that match given patterns
-vis an option that invert the sense of matching (select non-matching lines)
'^string_to_exclude'is the pattern (regex) to exclude (
^means start of line)
