Time for another thread about using sh(1) as an interactive shell. I thought about this while claining up my configuration file. Did you recently revised yours?

Thanks for sharing. That `ch` function does look neat, will have to try that. The only one I have that is worth sharing this nice little compressed file extractor function. I cannot tell you where I found it, but I came accross it somewhere on GitHub a little while ago and it has been nice not having to remember all the different `tar` commands. ``` # ARCHIVE EXTRACTION # usage: ex ex () { if [ -f $1 ] ; then case $1 in *.tar.bz2) tar xjf $1 ;; *.tar.gz) tar xzf $1 ;; *.tar.xz) tar xf $1 ;; *.tar) tar xf $1 ;; *.tar.zst) uzstd $1 ;; *.bz2) bunzip2 $1 ;; *.rar) unrar x $1 ;; *.gz) gunzip $1 ;; *.tbz2) tar xjf $1 ;; *.tgz) tar xzf $1 ;; *.zip) unzip $1 ;; *.Z) uncompress $1 ;; *.7z) 7z x $1 ;; *.deb) ar x $1 ;; *) echo "'$1' cannot be extracted via ex()" ;; esac else echo "'$1' is not a valid file" fi } ```

@"pfr"#p8708 I have a similar script to extract stuff, but having it in shrc is probably more convenient (I tend to miss transferring scripts across systems). Thanks a lot!

@"JuvenalUrbino"#p8701 `ch` function not working for me. What exactly is it supposed to do?

@"pfr"#p8729 you need to also include the q() function above. Code is from @"rvp"#168, as I mentioned in the file. See [BSD Tips and Tricks](https://www.unitedbsd.com/d/308-moritz-systems-bsd-tips-and-tricks/20) thread

> @"JuvenalUrbino"#p8730 you need to also include the q() function above Cool, that got it working. I was curious about shell functions a while back but then forgot about it. I had planned to turn all my [alieses into functions](https://www.unitedbsd.com/d/433-ksh-shell-functions/6). I just didn't have the time to really delve into it and it was (still is) a little over my head.

@"pfr"#p8760 > @"pfr"#p8760 I had planned to turn all my [alieses into functions](https://www.unitedbsd.com/d/433-ksh-shell-functions/6) I think they serve different purposes. Aliases are often used to replace standard commands for interactive use and are not expanded in non-interactive shells; moreover they can be easily undone with `unalias`

@"JuvenalUrbino"#p8769 So you dont think it really matters? I mean, my alias list is long, but creating functions would use more lines of code. Plus, so far my alias's serve their purpose so no point complicating things.. I suppose. Anyway, I do have a question related to this section: > @"JuvenalUrbino"#p8701 ``` #--- shell options --- # vi mode set -o vi # don't overwrite files with “>" set -o noclobber # PS command substitions set -o promptcmds # print pwd when changed set -o cdprint # export variables set -o allexport # filename completions set -o tabcomplete # disable nounset set +u ``` Mind explaining what these do? `set -o vi` vs `set -o emacs` I have it set to emacs. Why? I dont know.. I initially copied my `.shrc` from @"pin"#2 and never gave it another thought. However, I dont use (or know how to use) emacs so should I change it to `vi` or can I simply set it to use `vim` ? ``` # don't overwrite files with “>" set -o noclobber ``` Does this disble the use of writing to files witn `>` or does it simply add text to the existing file without overwriting what's in there?

@"pfr"#p8830 The fine sh(1) manual ;) ```txt Command Line Editing When sh is being used interactively from a terminal, the current command and the command history (see fc in the Built-ins section) can be edited using emacs-mode or vi-mode command-line editing. The command ‘set -o emacs’ (or -E option) enables emacs-mode editing. The command ‘set -o vi’ (or -V option) enables vi-mode editing and places the current shell process into vi insert mode. (See the Argument List Processing section above.) The vi-mode uses commands similar to a subset of those described in the vi(1) man page. With vi-mode enabled, sh can be switched between insert mode and command mode. It's similar to vi: pressing the ⟨ESC⟩ key will throw you into vi command mode. Pressing the ⟨return⟩ key while in command mode will pass the line to the shell. The emacs-mode uses commands similar to a subset available in the emacs editor. With emacs-mode enabled, special keys can be used to modify the text in the buffer using the· control key. sh uses the editline(3) library. See editline(7) for a list of the possible command bindings, and the default settings in emacs and vi modes. ``` Emacs mode mostly means it works similarly to other shell's defaults on other systems, emacs isn't a modal editor. vim wouldn't be a valid setting.

> @"pfr"#p8830 Does this disble the use of writing to files witn > or does it simply add text to the existing file without overwriting what's in there? Attempting to overwrite with '>' wil tell you that the file exists. This prevents unintentional overwriting while redirecting stdout to a file. You may still *create* files with '>' or append text to existing ones with '>>'. I set this option tor the very same reason while I also force interactive prompting for confirn before deleting. I am the clumsy and distracted kind of guy who would accidentallly lose important files. I learned from my mistakes.

pin I'm able to reproduce this and it looks like a ksh bug. NetBSD's ksh doesn't seem to notice a window size change when it is sitting idly at the prompt. Press enter once (or, run any command) and then ksh picks up the change. I'll see what I can do with it this weekend.

Also, have only one of JU's or my cd functions in your .shrc, not both. Having both around is both redundant and confusing. I suggest something like this in your .shrc:

...
. ~/.funcs/cd_ju.ksh
# . ~/.funcs/cd_rvp.ksh
...

Or, the other way around 😁

rvp it looks like a ksh bug

Cool, keep us posted if you get a fix for it.

I thought I would try with a clean .shrc without any other junk. So I tried with your cd function (which works slightly better) But I still do not get a stand alone tilde symbol when in my home directory.

.shrc :

# .shrc file for sh(1).

case "$-" in *i*)
    set -o emacs
    set -o noclobber

cd() {
        builtin cd "$@"
        if [[ x"$PWD" == x"$HOME"* ]]
        then    PS1=$(printf "\033[35m%s\033[00m \033[37m$\033[00m " "~/${PWD#$HOME}")
        else    PS1=$(printf "\033[35m%s\033[00m \033[37m$\033[00m " "$PWD")
        fi
}

Here's a quick patch for you to test (I'll work up a proper fix later):

I'll give it a go as soon as I can. Probably not before earliest on Monday.

pfr Hmm. Is $HOME a symlink?
If /home/dave is actually /usr/home/dave, then either:

Set export HOME=/usr/home/dave in ~/.profile, or
Change the cd command to: builtin cd -L "$@", or
Do set +o physical in ~/.shrc

(This is for ksh which defaults to `set -o physical--according to the man page; but that lies!)

pfr

rvp Is $HOME a symlink?

Don't think so...

/home/dave $ ls /usr/home
ls: /usr/home: No such file or directory

rvp or

Change the cd command to: builtin cd -L "$@", or

Do set +o physical in ~/.shrc

neither changes the prompt 🙁

pfr Run set -x to see what the shell's doing when it's executing the function. I tried your cd() function and it worked for me.

pfr

neubaer

/home/dave $ set -x
/home/dave $ cd
+ cd
/home/dave $

neubaer

pfr Mea culpa, you have to add set -x to the function, best have it as the first line.

lol. my bad 🙂 gotta sleep, will try tomorrow

pfr Odd. The pattern match is only failing for $HOME. Try this version:

cd() {
	set -x    # tron
	command cd -- "$@"
	# if [[ "${PWD}/" == "${HOME}/"* ]]
	# if echo "${PWD}/" | grep -q -- "^${HOME}/"
	if expr "${PWD}/" : "${HOME}/" >/dev/null
	then	PS1=$(printf '\033[35m%s\033[0m \033[1;37m$\033[0m ' "~${PWD#$HOME}")
	else	PS1=$(printf '\033[35m%s\033[0m \033[1;37m$\033[0m ' "$PWD")
	fi
	set +x    # troff
}
cd

Post output of above and also of:

printf '%s\n' "$SHELL" "$0" "$-" "$(id)"

Email me a copy of your ksh as well for good measure.

Are those commented out lines necessary?
Anyway, this one doesn't even work for the Downloads directory:

$ cd

~~Will do~~ Done.

rvp

pfr expr /home/dave/ : /home/dave//

There's the problem. By the time this function is called, something has added a / to the end of your $HOME. However: since multiple /s should be treated like a single / & trailing /s denote the same dir., I've fixed my original script. It should now be more robust.

pfr

rvp
Yes! this worked. Thank you 🙂

The only thing that isn't quite right is the $ is bold for some reason and looks like its from a char set and not part of the font.

Anyway to change this?

Also, I dont know if you can answer this, but I'm just curious why my ksh behaves like this when most others didn't have the same issue.

rvp

pfr Anyway to change this?

Change the 1;37m to 1;5;37m
(Careful with the typing, otherwise the prompt'll get messed up.)

pfr I'm just curious why my ksh behaves like this when most others didn't have the same issue.

It's not ksh; it's something in your setup which is adding that /. Check your startup scripts. Also /etc/passwd dave's home dir.

pfr

rvp Change the 1;37m to 1;5;37m

That didn't appear to change anything unfortunatly 🙁
~~Which manual should I read to figure out what all those numbers mean?~~
EDIT: ANSI escape sequences 👍️ 1;0m fixed it.

rvp It's not ksh; it's something in your setup which is adding that /. Check your startup scripts. Also /etc/passwd dave's home dir.

Hmm ok, I'll investigate this some more.
Thanks again for all your help trouble shooting 🍻
