Tip: show the last 3 directories in the shell prompt
tcsh: have the following in .cshrc (or .tcshrc)
zsh: have the following in .zshrc
bash: have the following in .bashrc
Lacking direct support this is a good approximation.

When I login to a specific machine (running Solaris 2.8; actually serveral machines behave this way), with a known good account, I don't get any shell prompt, and no screen responses to various commands such as ID and PWD. Any ideas on what is causing this, and how to change this behavior? (2 Replies)
Hello,
I wanted to setup user friendly ksh command prompt, by typing first character of files or directories and then tab bring up whole word. No need to type whole file/directory/command names.
Example:
cat a file like university
just typing un and then tab bring up whole university wod.... (3 Replies)
I have a directory that I want to just list the items when going to the URL instead of having an index.html page in the folder. I keep getting a 403 forbidden even though it is in my document root.
I tried to add:
Alias /keys/ "/var/www/html/keys/"
<Directory "/var/www/html/keys">

Hi All,
This is an embarrassingly simple question and couldn't think of "keywords" to search for the answer, but how do I change my UNIX/KSH prompt to show the machine name and my "current" but not "full" directory?
For example: if the machine name is "machine" and I'm currently in... (4 Replies)
Hello all, i'm stumped.... I need to list all directories with all there info and exclude the files, then vice versa. I am not sure if I need to string several ls commands together or how to even do that. I believe I need to do some variation of ls -l but need to figure out how to take out the... (5 Replies)

A couple of times there was the question: in a directory hierarchy how to display the deepest directories only.
For example in Help with listing only subfolders.
My hot solution at that time was (in short)
find . -depth -type d | awk -F / 'NF>=p; {p=NF}'
But another article has opened my eyes... (6 Replies)
We have regularly questions about how to create users and user accounts. But regularly user accounts need to be deleted too. It is quite easy to delete the user account itself but usually the HOME directory of the user remains.
It is good style to remove these directories but simply deleting... (3 Replies)

which
WHICH(1) General Commands Manual WHICH(1)NAME
which - shows the full path of (shell) commands.
SYNOPSIS
which [options] [--] programname [...]
DESCRIPTION
Which takes one or more arguments. For each of its arguments it prints to stdout the full path of the executables that would have been exe-
cuted when this argument had been entered at the shell prompt. It does this by searching for an executable or script in the directories
listed in the environment variable PATH using the same algorithm as bash(1).
This man page is generated from the file which.texinfo.
OPTIONS --all, -a
Print all matching executables in PATH, not just the first.
--read-alias, -i
Read aliases from stdin, reporting matching ones on stdout. This is useful in combination with using an alias for which itself. For
example
alias which='alias | which -i'.
--skip-alias
Ignore option `--read-alias', if any. This is useful to explicity search for normal binaries, while using the `--read-alias' option in
an alias or function for which.
--read-functions
Read shell function definitions from stdin, reporting matching ones on stdout. This is useful in combination with using a shell func-
tion for which itself. For example:
which() { declare -f | which --read-functions $@ }
export -f which
--skip-functions
Ignore option `--read-functions', if any. This is useful to explicity search for normal binaries, while using the `--read-functions'
option in an alias or function for which.
--skip-dot
Skip directories in PATH that start with a dot.
--skip-tilde
Skip directories in PATH that start with a tilde and executables which reside in the HOME directory.
--show-dot
If a directory in PATH starts with a dot and a matching executable was found for that path, then print "./programname" rather than the
full path.
--show-tilde
Output a tilde when a directory matches the HOME directory. This option is ignored when which is invoked as root.
--tty-only
Stop processing options on the right if not on tty.
--version,-v,-V
Print version information on standard output then exit successfully.
--help
Print usage information on standard output then exit successfully.
RETURN VALUE
Which returns the number of failed arguments, or -1 when no `programname' was given.
EXAMPLE
The recommended way to use this utility is by adding an alias (C shell) or shell function (Bourne shell) for which like the following:
[ba]sh:
which ()
{
(alias; declare -f) | /usr/bin/which --tty-only --read-alias --read-functions --show-tilde --show-dot $@
}
export -f which
[t]csh:
alias which 'alias | /usr/bin/which --tty-only --read-alias --show-dot --show-tilde'
This will print the readable ~/ and ./ when starting which from your prompt, while still printing the full path when used from a script:
> which q2
~/bin/q2
> echo `which q2`
/home/carlo/bin/q2
BUGS
The HOME directory is determined by looking for the HOME environment variable, which aborts when this variable doesn't exist. Which will
consider two equivalent directories to be different when one of them contains a path with a symbolic link.
