pipestatus 0.5.0 (Default branch)

pipestatus is a source file for UNIX/POSIX shellsthat provides set of functions for obtaining theexit status of every program in a pipe withoutusing non-portable extensions. Most shells, suchas BSD /bin/sh, ksh, pdksh, ash, bash, dash, mksh,and zsh are supported.License: Public DomainChanges:
"check_status_re" and therefore "runpipe_re" use"grep -E" instead of "grep" in order to simplifythe regexp that contains exit statuses of 2 ormore digits. Formally speaking, this breaksbackward compatibility. If the PIPESTATUS_VERBOSEvariable is set to a non-empty string, then thecheck_status0 and check_status_re functions printan error message to stderr.
