ls output with mode in octal

this requires the use of a throwaway file. it outputs a shell function. assuming the throwaway file is f.tmp usage: >f.tmp;lso f.tmp > f.tmp; . f.tmp;rm f.tmp;lso -l ... notes: credit epons.org for the idea. however his version did not account for the sticky bit and other special cases. many of the 4096 permutations of file permissions make no practical sense. but chmod will still create them. one can achieve the same sort of octal output with stat(1), if that utility is available. here's another version to account for systems with seq(1) instead of jot(1): lso(){ case $# in 1) { case $(uname) in FreeBSD) jot -w '%04d' 7778 0000 7777 ;; *) seq -w 0000 7777 ;; esac; } \ |sed ' /[89]/d s,.*,printf '"'"'& '"'"';chmod & '"$1"';ls -l '"$1"'|sed s/-/./,' \ |sh \ |{ echo "lso(){"; echo "ls \$@ \\"; echo " |sed '"; sed ' s, ,@,2; s,@.*,,; s,$.* $$.*$,s/\2/\1/,; s, ,,'; echo \'; echo }; }; ;; *) echo "usage: lso tmp-file"; ;; esac; } this won't print out types[1]. but its purpose is not to examine types. its focus is on mode and its purpose is to make mode easier to read (assuming one finds octal easier to read). 1. one could of course argue "everything is a file", but not always a "regular" one. e.g., a "directory" is really just a file comprising a list.
