in reply to How to check if a string contains more than 1 character?

OK...another (useless?) oneliner:

Karls-Mac-mini:monks karl$ export foo=b Karls-Mac-mini:monks karl$ echo ${foo} | perl -ne '( /.{2,}/ ) ? exit +1 : exit 0;' Karls-Mac-mini:monks karl$ echo $? Karls-Mac-mini:monks karl$ export foo=bar Karls-Mac-mini:monks karl$ echo ${foo} | perl -ne '( /.{2,}/ ) ? exit +1 : exit 0;' Karls-Mac-mini:monks karl$ echo $?

Regards, Karl
