Michael Forney said that he was trying to run on a system that did NOT
support head -number and tail +number old-style format.
This is why I suggested use of 'sed' instead of 'head' and 'tail'. The
sed command predates both head and tail and the following idiom in sed
should be common going back to at least 1984 when I used sed in this way
on the following systems:
Berkeley Software Distribution (4.4 BSD-Lite).
Mt Xinu 4.3
AIX 3 (1989) - AIX 4 (1994)
HP/UX System V (1989)
SunOS 3.0Beta1 (1986) thru Soliars 11
FreeBSD 2.2.6 thru FreeBSD/11
OpenBSD 2.7
Cray X/MP
I recommend the change from
(head -2 .depend; tail +3 .depend | sort) >.depend.tmp
to
(sed 2q .depend; sed 1,2d .depend | sort) > .depend.tmp
should do the job correctly for all instances of sed I have ever used.
Failing this solution, coming up with a 'configure' script test might be
possible that provides for a compatibility test for using of -n options
for head and tail
Be safe, stay healthy,
