true
Return a zero exit status (always true)
TLDR
Return a successful exit code
$ true
Make a command always exit with 0
$ [command] || true
SYNOPSIS
true
DESCRIPTION
true does nothing except return a successful (zero) exit status. It's used in shell scripts where a command is syntactically required but no action is needed, or to create infinite loops.
CAVEATS
Always returns exit code 0. The shell built-in may be faster than /bin/true.
COMMON USES
while true; do ...; done - Infinite loop
cmd || true - Ignore failure
: > file - Truncate file (: is similar)
