[SOLVED] Getting some errors while executing a shell script.

Satyaveer Arya · 07-12-2012, 01:23 AM

Hi,

I got a script after searching on google, which checks for errors in error_log file. And I am learning shell scripting but not much proficient in shell scripting till now. This script takes /var/log/httpd/error_log as parameter when we execute this script.
So, when I am executing this script I am getting these errors, mentioned below:

Quote:

[root@web ~]# ./weberrors /var/log/httpd/error_log
Input file /var/log/httpd/error_log has 231992 entries.
Entries from [Sun Jul 08 04:50:37 2012] to [Thu Jul 12 11:41:13 2012]

File does not exist errors:
18837 http://www.icfre.org/
9118 http://www.icfre.org/sitesearch.php
8681 /var/www/html/favicon.ico
6861 /www/favicon.ico
4956 http://www.icfre.gov.in/

script not found or unable to stat errors:
4 /var/www/cgi-bin/progress.cgi
grep: Unmatched ( or \(
cut: the delimiter must be a single character
Try `cut --help' for more information.

And non-error messages occurring in the log file:
grep: Unmatched ( or \(

I have attached the script. You can check the script.
Can anyone please help me in solving this script?

The 'cut' error is because it's missing a space on line 46. Change:

Code:

sed 's/\[error\]/\`/' | cut -d\` -f2 | cut -d\ -f4- | \

to

Code:

sed 's/\[error\]/\`/' | cut -d\` -f2 | cut -d\  -f4- | \

(i.e. two spaces after the backslash on the second 'cut', not one)

Still working on the others, I'm afraid...

EDIT: AHA! Yeah, the thing that's messing the other bit up is the fact they've put a newline in the 'screen' variable. Just put it all on one line. From:

Code:

screen="(File does not exist|Invalid error redirect|premature EOF|Premature end of
script|script not found)"

to

Code:

screen="(File does not exist|Invalid error redirect|premature EOF|Premature end of script|script not found)"

It's a nice script, by the way

Hi Snark,

Thank you very much for solving the problem. I did exactly as you said and the script is working fine now.

Thank You!
