The Problem:
I wanted to send myself a listing of files in a directory from a remote
machine.
How I solved it:
$ ls -l /path/foo > bar
$ mail -s"listing of /path/foo" [EMAIL PROTECTED] < bar
How I tried to solve it:
$ mail -s"bleh" [EMAIL PROTECTED] < `ls -l /path/foo`
does not work because '`' causes the shell to use the output as a list of
files
$ mail -s"bleh" [EMAIL PROTECTED] < eval "ls -l /path/foo"
does not work because eval is evaluated as a filename which does not exist
$ ls -l /path/foo | mail -s"bleh"...
does not work because mail can't be the target of a pipe
more exotic variants:
$ mail -s"blah" [EMAIL PROTECTED] < (ls -l /path/foo)
unexpected token '('
$ mail -s"blah" [EMAIL PROTECTED] < $(ls -l /path/foo)
no such file
What I'm seeking:
the bit of syntax that will let me use the output of a command
as the input to mail obviously, but more generally
$ command1 < ?command2?
I was trying this using /bin/sh on OpenBSD but a good solution would work
on most POSIX'ly compliant shells.
Suggestions?
