Hi,
I am having problems using grep to extract only 3,4 or 5 digit numbers from a text file, using:
grep '\<\{3,5\}\>' test.txt
or
grep '\{3,5\}' test.txt
or
egrep '{3,5}' test.txt
I would appreciate any help that anyone can give me
thanks (1 Reply)
Hi all,
For a intro UNIX course I'm taking, I need to use the command "tr" to display a file on standard output without any newlines (all on one line).

Thanks. (3 Replies)
