grep regex with hyphens and white spaces

I am trying to fetch a line with the following information -a string1 -b file1.txt -c string3 using grep.

I tried grep -v grep | grep '[b][:space:] *.txt *[c]' grep -v grep | grep '[b] *.txt *[c]'

string1, string3 and file1 are variables. So I am looking for solutions using wild characters.

But there is nothing returned. Any help will be appreciated.

You may use this grep:

grep -- '-a [^[:blank:]]* -b [^[:blank:]]*.txt -c [^[:blank:]]*' *.txt
  • [^[:blank:]] matches any non-whitespace character.
  • -- separates options and pattern arguments.
