Perhaps coreutils should teach 'env' a command-line option to forcefully
reset SIGPIPE back to default behavior [...] If we
did that, then even if your sh is started with SIGPIPE ignored (so that
the shell itself can't restore default behavior), you could do this
theoretical invocation:
$ seq 9999 | env --default-signal PIPE sort -n | sed 5q | wc -l
5
That is a nice idea, I could've used it myself couple of times.
Attached a suggested patch.
If this seems like a good direction, I'll complete it with NEWS/docs/etc.
Usage is:
env --default-signal=PIPE
env -P ##shortcut to reset SIGPIPE
env --default-signal=PIPE,INT,FOO
This also works nicely with the recent 'env -S' option,
so a script like so can always start with default SIGPIPE handler:
#!/usr/bin/env -S -P sh
seq inf | head -n1
