# 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 ﻿-v:

grep -v '^string_to_exclude' file.txt

• ﻿grep is a linux command that print lines that match given patterns
• ﻿-v is 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)
