Subject: detect pipe
Date: Wed, 27 Jan 2021 08:45:24 -0800	[thread overview]
Message-ID: <e7dc936d-4149-7882-5ac9-24e34b268985@eastlink.ca> (raw)

I have a function that as used this test for piping quite reliably:

     if [ ! -t 0 ]; then

... but today it stopped working.  I thought I might have broken 
something in the function so tried backups and it would flicker in and 
out of effect, work one time and not the next.  Searching the web I see 
that apparently the above test is not 100% reliable. True?  If so, is 
there a better way?  This is probably not strictly a zsh problem but the 
randomness of it working intermittently suggests some time lag or delay 
or something. Perhaps the test needs time to think?  Someone might have 
a workaround even if this isn't zsh's fault.
