[ferret_users] 'head -1' syntax causes Fprint to fail
We have a ferret script that causes the error message:
head -1 t_ref
grep -s ^GKSM
head: `-1' option is obsolete; use `-n 1'
Try `head --help' for more information.
when invoking Fprint with "spawn Fprint -o ($psfile) ...".
What's odd is that other scripts don't cause 'head' to abort like this.
info coreutils head
explains that
POSIX 1003.1-2001 does not allow 'head -1' syntax. Anyone know the
cause for 'head' to be in or out of obsolete mode in the context of
Fprint and ferret?
From the tcsh shell, the following works:
head -1 t_ref
GKSM...
which head
/usr/bin/head
head --version
head (coreutils) 5.2.1
