UNIX for Dummies Questions & Answers

There are are lots of examples of piping output FROM the 'ls' command TO another command, but how does one pipe output TO the 'ls -l' command?

For example, use 'which' to find a file, then use 'ls -l' to view the permissions, groups, etc. in a single step:

which <filename> | ls -l

returns a long listing of the current directory, not a long listing of the filename and path returned by the 'which' command.

which <filename> | ls -l -

returns a file not found error on '-'

Suggestions, please. Thanks!

Code:

ls -l `which <filename>`

Thanks, Ikon!

Code:

a=$(which filename) && ls -l $a

Thanks for that alternate solution, jlliagre!

That's better than my idea of doing the same thing with multiple commands on a single commandline with a command separator between them.
