Lisa,
Try:
export FILE=$1
print File is $FILE
for PAGER in ${*-$(awk -v FILE=$FILE '!/^#/ {print FILE}'
dba_oncall.txt)};
do
print $PAGER

Subject: awk and ksh question
Hello everyone,
I'm trying to awk through a text file and use that with a passed-in
message to send email. Here's an example of my text file:
# DBA's on call
[EMAIL PROTECTED] # Lisa pager
[EMAIL PROTECTED] # Lisa email
Here's my awk statement, which works properly
awk '!/^#/ {print $1}' filename.txt
prints the first entry in each file and skips any lines starting with #.
So I put it in a loop. I don't quite understand all the syntax here, I'm
pulling the exact syntax out of Steve Adams' database check script.
--
for PAGER in ${*-$(awk '!/^#/ {print $1}' dba_oncall.txt)}
do
print $PAGER
done
--
Works fine.
Now when I try to pass in a parameter in $1 (which I mean to be the email
message), awk grabs it and the script no longer works. Like this
--
export FILE=$1
print File is $FILE
for PAGER in ${*-$(awk '!/^#/ {print $1}' dba_oncall.txt)};
do
print $PAGER
done
--
This prints the name of the file in both print statements, before and
inside the loop. What am I doing wrong?
Also if anyone can explain in a nutshell what the ${} means (I think it
means consider the results as a variable) and the * and - and $() means in
the for/do loop syntax I would be grateful. I'm leafing through my ksh
book but I think this is several specific functions all slapped together.
Thanks to anyone that can help pull my head out of the sand...
