That is the correct and required behavior. But cut is actually very poor at cutting out fields. I only very rarely use it for such things. I recommend using awk for that purpose. > That makes impossible to cut columns out of "tar tvf" listings. The sixth field of a tar tvf listing is simply the filename. If you wish to remove the other information then simply do not print it with tar. That is, instad of: tar tvf foo.tar | sed 's/ */\t/g' | cut -f6 Use this instead: tar tf foo.tar Without the 'v' option only the filenames will be printed. > Example: the input file is > a b c > a b c > a b c > cat test | cut -d ' ' -f 2- gives > b c > b c > b c > instead of > b c > b c > b c That is the required behavior for cut. After 30 years it would be impossible to change it now. If you want to group all whitespace together when calling out fields I recommend using awk which is much better at printing fields such as this: echo " a b c" | awk '{print$2}' echo " a b c" | awk '{print$NF}' Bob _______________________________________________ Bug-coreutils mailing list [email protected] http://lists.gnu.org/mailman/listinfo/bug-coreutils
