Say I want to print only character. How do you grep a character only and then store that into a shell variable?
grep search pattern for single character:
.: Any single character
[...]: Any single character in the bracketed list or range
So to grep a character only, you will do:
grep '.' filename
To match only one character:
grep -w '.' filename result=$(grep -w '.' filename) echo "$result"
thank you. I did it as
grep -w '[[:alpha:]]' data005.file grep -w '[[:alnum:]]' data006.file
it took me while but it is now working.
