Minor question about the code of the init script

In reading bedrock init's code, I found references to echo and cut, apparently to extract part of a string.

# Around line 364

init_timeout="$(cfg_values "init" "timeout")"
def_tuple="$(cfg_values "init" "default")"
def_stratum="$(deref "$(echo "${def_tuple}" | cut -d: -f1)")"
def_cmd="$(echo "${def_tuple}" | cut -d: -f2-)"
def_tuple should be of the form

As described in the shipped /etc/bedrock.conf file

# Init to utilize by default if timeout expires.  Format is
#     default = <stratum>:<path>
# For example, to use void's /sbin/init, use:
#     default = void:/sbin/init
default =
If that's the case, then I propose to replace echo and cut with bash's % and # string operators, like so :

# Around line 364

init_timeout="$(cfg_values "init" "timeout")"
def_tuple="$(cfg_values "init" "default")"
def_stratum="$(deref ${def_tuple%:*}"
def_cmd="$(deref ${def_tuple#*:}"
ychaouche#ychaouche-PC 15:47:32 ~/MUSIQUE/CONTENT/BRASIL $ def_tuple=void:/sbin/init
ychaouche#ychaouche-PC 17:48:01 ~/MUSIQUE/CONTENT/BRASIL $ echo ${def_tuple%:*}
ychaouche#ychaouche-PC 17:48:06 ~/MUSIQUE/CONTENT/BRASIL $ echo ${def_tuple#*:}
ychaouche#ychaouche-PC 17:48:11 ~/MUSIQUE/CONTENT/BRASIL $

Comments ?

This isn't running in bash, but the busybox sh we are using does provide that as well. That should work.

However, I don't want to make changes to working code that don't have discernible improvements, as all it does is introduce unnecessary risk without meaningful benefit. There's work towards a proper test suite infrastructure. Once that's in place with adequate tests to confirm such changes won't break something we can revisit the possibility.


bash scripting, strings
