gzip and gunzip

[Todd McDaniel_1]

Okay, I downloaded 1.3.3 gzip and ./configure and make...

I have 1.3.3 gzip now, but how do I compile 1.3.3 gunzip? what am I missing?

for HPUX of course...

gzip and gunzip are the same executable! You simply need to link them and you are done. The code simply looks at argv[0] and asks itself is my name "gzip" or "gunzip" and acts accordingly. This is a standard UNIX idiom.

I AM an idiom :D

Hi,

these two files are hard linked to be seen with ls -lisa *zip*
Use ln, not ln -s.
If exist knowledge(*)
then
update thispost set points=0
fi

Michael,

Actually, I just cp gzip gunzip; cp gzip gzcat...

And they work fine!!

# ls -lisa g*
40932 586 -rwx--x--x 1 root sys 299200 Mar 19 11:03 gunzip
45109 586 -rwx--x--x 1 root sys 299200 Mar 19 11:07 gzcat
40763 586 -rwx--x--x 1 root sys 299200 Mar 19 10:38 gzip

I think I will redo them as ln so they are technically correct...

Todd, notice that I said they are the same executable. That was intentional wording. They are only the same if the are linked (hard). That way if you copy or replace one, you implicitly replace the other.

Actually, your makefile should have created this link for you so you should really fix the "problem" there.
