[SOLVED] bash >| redirection

fukawi2 · 2011-02-26 22:15:40

I was looking at rc.sysinit just now, and noticed use of the redirection operator ">|"

Google doesn't return much for me, I guess it doesn't like those characters.

What does >| do?

From bash(1) manpage:

Redirecting Output                                                
   [...]
   The general format for redirecting output is:

      [n]>word

   If  the  redirection operator is >, and the noclobber option to
   the set builtin has been enabled, the redirection will fail  if
   the  file  whose name results from the expansion of word exists
   and is a regular file.  If the redirection operator is  >|,  or
   the  redirection  operator is > and the noclobber option to the
   set  builtin  command  is  not  enabled,  the  redirection   is
   attempted even if the file named by word exists.

not sure about bash but i know in zsh it's just like > but truncates to zero first and forces clobbering even if a clobber option is unset.
