UNIX for Dummies Questions & Answers

I have three lines in a log that I want to check to make sure that they say the following (mm/dd/yyyy and hh:mm:ss changes depending in when the log is generated):

'*** Testing file for mm/dd/yyyy'
'*** End of procedure! Time was: hh:mm:ss'
'*** End ***'

I did some sed and cut and ended up with something like this (the constant portion):

Code:

if [[ $first = '***            Testing file' ]] &&
   [[ $second = '***            End of procedure Time was:!' ]] &&
   [[ $third = '*** End ***' ]]; then
  do something
else
  handle error
fi

When I echo out the uncut lines (as is) compared to the cut lines, they match up to the point where I did the cut:

'*** Testing file for mm/dd/yyyy'
'*** Testing file for'
'*** End of procedure! Time was: hh:mm:ss'
'*** End of procedure! Time was'
'*** End ***'
'*** End ***'

Technically, my if-then statement matches the cut lines but the else ALWAYS gets executed even though the test echo statements I did seemt to match exactly to the dot...what is going on?? I can't figure it out. I thought it was some blanks somewhere but that did not appear to be the case. Anyone??

That's some very creative syntax you have there. I've never seen an "if" statement like that.

But look where you are checking $second. You have mispositioned the explanation point in your constant.

The '!' in the wrong position was a typo but that didn't do anything..I'm still getting the error like it is not matching.

Also, is that wrong to write an if-else-then like that or you're just making an observation. I have tons of codes with that type of if-else-then...hehe

Thanks.

Would be even better if someone can help me figure out how to check for the entire line content, keeping in mind that the pattern would still be:

*** Testing file for mm/dd/yyyy' '*** End of procedure! Time was: hh:mm:ss'

Would this make sense for pattern mm/dd/yyyy in the first line?

[0-1][0-2]/[0-3][0-9]/200[3-9]?

Thanks.

If what you said was true, this should be working. This script

Code:

#! /usr/bin/ksh

first='*** Testing file'
second='*** End of procedure Time was:!'
third='*** End ***'

if [[ $first = '*** Testing file' ]] &&
   [[ $second = '*** End of procedure Time was:!' ]] &&
   [[ $third = '*** End ***' ]]; then
       echo ok
else
       echo not ok
fi
exit 0

will print "ok" when I run it. Give it it try and see if it works for you.

And try:
echo first = \"${first}\"
Maybe you have trailing blanks.

It didn't work when I made the change as you've suggestd. Still causing error handling to be performed. It is only a problem on those lines where I did the cut. If I compare the line as is (last line) then it always executes successfully. This is why I am not sure if it is something else. I am not sure why the trimmed lines would be a problem though because what I trimmed and what I compared the trimmed lines to are identical as far as I can tell...

Maybe you could put echo $first, echo $second and echo $third after "else" in the code just to make sure the values are what you intend them to be..
