Ew, csh.
Man pages are also to be found under /usr/share/man on Linux
systems. And /usr/local/man and /usr/local/share/man.
In sh or bash, the loop would look like:
for i in $(ls -R) ; do
echo $i
cat $i | troff -man | lpr -Pyourpsprinter
done
(And instead of backticks, $(command). $() nests, which backticks
don't.)
Adam
And just to be weird:
find . -type f | while read i;do echo "$i"; troff -man <"$i" | lpr
-Pyoupsprinter;done
Both of the previous posters get a "useless use of cat" award.
What, you've never typed the wrong angle-bracket?
Permissions can come into play too:
[EMAIL PROTECTED] ~]$ sudo ls -l /var/log/squid/access.log
-rw-r--r-- 1 squid squid 0 Jan 21 04:02 /var/log/squid/access.log
[EMAIL PROTECTED] ~]$ sudo ls -l /var/log/squid/*
/bin/ls: /var/log/squid/*: No such file or directory
[EMAIL PROTECTED] ~]$ head </var/log/squid/access.lo*
-bash: /var/log/squid/access.lo*: Permission denied
[EMAIL PROTECTED] ~]$ head </var/log/squid/access.log
-bash: /var/log/squid/access.log: Permission denied
[EMAIL PROTECTED] ~]$
and many times I find I'm wanting to change this:
grep something fromhere | ....
to something like this:
(gunzip -c *log.ga;cat *.log) | grep something
which is ease if I start with the cat.
