Hmm... I hate to sound too critical here but I can't restrain making comments about that command line. It is working very much too hard to perform the function of listing out a directory with the inode change timestamps listed. (And also that is not sufficient to solve the original poster's question either.) But back to that command line... > TMP=`ls -Aa` The ls -a option overrides the -A option. Therefore 'ls -Aa' is the same as 'ls -a'. But you probably wanted 'ls -A' there. > for x in $TMP ; do Of course files with whitespace in them cause trouble here. An extra splitting is introduced here that will split files with whitespace apart. > echo -n "$x - " Use of 'echo' with options is a portability nightmare. Better to use 'printf' in that case. > stat $x | tac | head -1 This is functionally the same as asking stat to output only the time of last change directly. stat --format %z $x > echo "" why the extra blank line? Overall this is almost the same as using 'ls' directly. ls -Aclog Bob
