Issue
I've got a file myfile
. I want to find lines that includes following pattern:
MyWebsite/1234
somecharactersstringswhitespacesMyWebsite/987somecharactersstringswhitespaces
There can be 1 or more numbers after MyWebsite
.
I have tried following:
grep ".*MyWebsite[0-9]\{1,\}" myfile
grep "MyWebsite[0-9]\{1,\}" myfile
grep MyWebsite"[0-9]\{1,\}" myfile
grep -E ".*MyWebsite/[0-9]\{1,\}.*" myfile
None of them worked, even if intuition and logic says that should be good.
Solution
grep 'MyWebsite/[0-9]\+' myfile
should work. On your first 3 regexes, you missed the /
and on the last, you shouldn't have escaped the {
and }
, but otherwise you were pretty good. It's more concise to use +
rather than {1,}
though, and the version of regex that grep uses by default (a variant of POSIX BRE) requires it to be escaped.
