We are using a shell-function to set the prompt based on return code -
it works fine in 17.01 / 18.06 / 19.07, however in current master when
the function is run the terminal/ssh session hangs.
how to reproduce:
<--- hang.sh:
#!/bin/sh
You could add following line here to check where it hangs:
set -x
prompt_set() {
face() {
local rc=$?
case "$rc" in
0) printf '%s' "$1" ;;
*) printf '%s' "$2" ; return $rc ;;
esac
}
local e='\[\e' # start escape-sequence
local c='\]' # close escape-sequence
local user='\u'
local wdir='\w' # workdir
local host='\h' # short form
local reset="${e}[0m${c}" # all attributes
local white="${e}[37m${c}"
local cyan="${e}[36m${c}"
local yellow="${e}[33;1m${c}" # bold
local green="${e}[32m${c}"
local red="${e}[31m${c}"
local ok="${green}:)"
local bad="${red}8("
# e.g. user@hostname:~ :)
export PS1="${cyan}${user}$white@${green}$host:${yellow}$wdir \$(
face '$ok' '$bad' ) $reset"
}
prompt_set
-->
now source the file:
. ./hang.sh
shellcheck does not complain - I'm writing because I'm not sure wether
this invalid sh that happened to work anyway or is this a
bug/regression in ash?
