Hi
I wanted to know if there is an option in grep command to show the number of results (not the number of lines of findings).
Thanks

When I type a command at the command line it supplies one result and the exact same command in a script
egrep '^01|^02|^03|^04' file > fileout

same count in the script yields a count of 23492
is there any reason this could be happening. (1 Reply)
