Converting percentage to a number

[shawnk]

Hello,

I am trying to use the awk command to print two columns. One of them has a percentage value. This is for file system monitoring. When i try to read it from a file it does not recognize the precent sign and ignores it. How can i convert it or skip the % sign when using this command?

Any help would be appreciated.

Thanks.
Shawn

Adding a sub() statement to your awk code that deletes the % from the df() output should work. The above syntax should work on your system (AIX & Pains or Solaris?); I'm still using a 1988 version of AT&T's AWK book.

Your code is sub-optimal, but that don't matter because it isn't running 1,000,000 times a second. It'll work.

That worked perfect but now i get this error msg for the next line.
My dumb brain can't figure out how to fix it :(

if [ `cat fs_usage |awk '{print $2}` -gt 36 ]

I tried to change it and put another quotation mark but it didn't solve the issue.

"0403-012 A test command parameter is not vaild."

That's what happens when you've been looking at the problem too long. I'm going through the same thing now on my own project ('updating' Smoothwall Express to use LFS 6.4). Boy am I overlooking stuff that doesn't become obvious very quickly! :( :(

Your awk code is missing the closing apostrophe. And you'll probably find $1 has the numeric value to compare.

Thanks for your help previously.
