NAME¶execlineb - command launcher for execline scripts
SYNOPSIS¶execlineb [ -p | -P | -S nmin | -s nmin ] [ -q | -w | -W ] [ -c commandline ] script args
- -c commandline
- execute commandline, do not look for a file.
Options for environment management¶
- will bypass the push phase: the current frame of positional parameters will be overwritten. The script will not be reentrant
- 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 after nmin 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.
- same as EXECLINE_STRICT is unset.
They won't complain at all.
- 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.
- 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/.
