| You want in your Makefile something along the lines of:
|=20
| somefilename:
| awk -F: '{print $$1,$$2}' < /etc/master.passwd > $@
|=20
Hi giorgos,
I've tried my hands on awk today ;).
The command below seems to do what I want when I use it on the command
line
cat master.passwd.test | awk -F ":" '{if ($3>999) {print $1":"$2}}' > autht=
ab
However, with my inexperience, I cannot conjure up a Makefile to use it
with. My Makefile is something like this;
##
authtab:
cat master.passwd.test | awk -F ":" '{if ($3>999) {print $1":"$2}}'=20
##
In all that I expect it to generate the file called authtab.
If I try your redirects (BTW what does $@ represent?) It generates errors
alligator# make
awk -F ":" '{if (>999) {print ":"}}' < master.passwd.test > authtab
awk: cmd. line:1: {if (>999) {print ":"}}
awk: cmd. line:1: ^ syntax error
*** Error code 1
Stop in /etc/Exim.
I don't get where the $3 disappears to.
I've read the 'make' man page but still it just doesn't ring a bell.
I'm certain someone already sees my mistake, yes? Something that's missing
in the Makefile??
TIA
-Wash
