Features

• written in shell script, so you never really leave the shell
• text-based graphical user interface
• no dependencies except a POSIX shell and core utils
• controlled with arrow keys and some vim-like shortcuts
• may be sourced to run in the current shell environment (using ". lscd")
• when sourced, it moves you to the last opened directory on exit
• may call an arbitrary file opener; uses "less" or ranger's "rifle" by default

lscd's Issues

Arrow keys not working

Looks like the escape sequence is not properly handled or different than expected. Using rxvt-unicode.

$ sed -n l
^[[A
\033[A$
^[[B
\033[B$
^[[D
\033[D$
^[[C
\033[C$

[POSIX] builtins `test` and `read`

Hi,

I have been trying to run lscd as script (with and without arguments), but I always get into the while loop with:

var/tmp/lscd: 185: read: Illegal option -n
var/tmp/lscd: 188: read: Illegal option -s
var/tmp/lscd: 189: read: Illegal option -s
var/tmp/lscd: 190: read: Illegal option -s
var/tmp/lscd: 191: [: unexpected operator
^C

My standard shell is:

$ readlink /bin/sh
dash

After reading this site, I recommend using test conditionals with single equals sign (=) and read only with option -r (because of POSIX compatibility).

Group directories before files

ls option --group-directories-first

Makes navigation easier.

[POSIX] SIGWINCH

Unfortunately, the signal SIGWINCH is not specified in the POSIX specification.

See: https://en.wikipedia.org/wiki/Unix_signal#POSIX_signals

Edit: only in 4.3BSD and Sun
