Command launcher for execline scripts
Usage
execlineb [{-p | -P | -S
nmin | -s
nmin}]
[{-q | -w | -W}]
[-c
commandline]
script
args
Options
-
-c commandline -
execute commandline, do not look for a file.
Options for environment management
-
-p -
will bypass the push phase: the current frame of positional parameters will be
overwritten. The script willnotbe reentrant
-
-P -
will bypass positional parameter handling completely: the environment will not be pushed, and positional parameters will be ignored. execlineb -P -c 'script' is equivalent to, but more efficient than, execlineb -c 'emptyenv -P script'. You should use the -P option only in standalone scripts that take no arguments, such as s6's or runit's run scripts.
-
-S nmin -
will substitute the positional parameters - up to at least nmin - but will not push nor set environment variables. execlineb -S3 -c 'script' is equivalent to, but more efficient than, execlineb -c 'elgetpositionals -P3 emptyenv -P script'.
-
-s nmin -
behaves just like the -S option, except that it defines $@ as the rest of the command line
afternmin arguments have been removed.
Options for block syntax checking
External execline commands that read blocks, like foreground, use the EXECLINE_STRICT environment variable.
Normally the EXECLINE_STRICT environment variable is inherited from the caller. You can force it unset, set to 1, or set to 2 by giving respectively the -q, -w or -W option to execlineb.
-
-q -
same as EXECLINE_STRICT is unset.
They won't complain at all.
-
-w -
same as EXECLINE_STRICT is set to 1.
They will print a warning message on stderr if they find their blocks not to be properly quoted.
-
-W -
same as EXECLINE_STRICT is set to 2.
They will also die.
Notes
On Debian GNU/Linux system, all binaries from execline package are installed in /usr/lib/execline/bin/.
For convenience, a script is provided as /usr/bin/execlineb, which adds /usr/lib/execline/bin/ to PATH when invoked.
