Jul 17	revised	Perl script, do cd on terminal added 327 characters in body
Jul 17	comment	Perl script, do cd on terminal Ah, I missed the "that runs a shell script" part. Which leaves an open question: Why??
Jul 17	answered	Perl script, do cd on terminal
Jul 17	comment	Perl script, do cd on terminal Your `b.pl` script would be more simply written as `system './a.sh'` -- and it's not particularly useful, since you might as well just invoke `a.sh` directly.
Jul 13	comment	Get a list of 3 letter commands on Mac OS X I'd pipe the output through something like `sed 's,.*/,,' \| sort -u` to remove the directory names and strip duplicates, and then perhaps through `fmt` so the output fits on my screen.
Jul 13	comment	Get a list of 3 letter commands on Mac OS X @WarrenYoung: `printf` is more flexible, and much more consistent, than `echo`. I agree that `echo` would almost certainly work fine in this case. Both `echo` and `printf` are built-in commands, at least in bash.
Jul 13	answered	Using VI to edit shell commands in UNIX
Jul 13	comment	Using VI to edit shell commands in UNIX That sets your default editor (for commands that pay attention to `$EDITOR`) to `vi`. It doesn't let you edit shell commands with `vi` (at least not directly).
Jul 3	comment	Origin of 'root' account I just looked at the Multics documents you linked to. They refer to the root directory (and the root volume), but there's no reference to a root user.
Jul 3	revised	Origin of 'root' account Add links for URLs
Jul 3	suggested	suggested edit on Origin of 'root' account
Jul 1	comment	random number needed @Alexios: `/dev/urandom` is almost always a better choice than `/dev/random`. See this question and my answer.
Jun 26	comment	bash equivalent of this use of tcsh “sched” command? Pre- vs. post- doesn't matter much; I can live with `$today` not being set correctly for the first command I execute after midnight.
Jun 26	comment	bash equivalent of this use of tcsh “sched” command? As I said in the question, `at` won't work; it can't set an environment variable in the shell from which it's invoked.
Jun 25	comment	bash equivalent of this use of tcsh “sched” command? That's likely to be the best I can do. The first disadvantage is what I'm most concerned about. We'll see of anyone else comes up with a better solution.
Jun 25	asked	bash equivalent of this use of tcsh “sched” command?
Jun 10	answered	Is it possible for a shell script to contain both tcsh and bash commands in the same script?
Jun 4	comment	In linux, would it be possible to run a script every day 3 minutes later than the previous day? To avoid drift, tell the script what time it's supposed to run and let it add 24h 3m to that.
May 25	answered	Run a command that is shadowed by an alias
May 25	comment	Run a command that is shadowed by an alias You have to know where the command is. On some systems, the division between `/bin` and `/usr/bin` is arbitrary.
