Due to all the positive feed-back, I actually tested the "ls -rt"-bit,
and sure enough, the 'r' makes ls list the newest files _last_, so you
DON'T want 'r'. This makes the correct command:
rm $(ls -t | sed '1,2d')
You should _still_ test it first using 'echo ', to make sure there are no subdirectories in there, and on general principles. Adapt to whatever you have in the directory.
Using the find command ensures that directories are skipped. The -maxdepth 0 restricts the search to the current directory:
rm $(find . -maxdepth 0 -type f | xargs ls -t| sed 1,2d)
However, this does not work, if you have files with spaces! Then the best is to use the -print0 and xargs -0 that uses zero-delimited strings instead of space delited strings. Also the rm must be run in a loop and with quotation marks around the filename:
find . -maxdepth 0 -type f -print0 | xargs -0 ls -t| sed 1,2d | while read f; do rm -f "$f" ; done
BR,
Roland
