modify content of file

Hi,

I have a problem. I am using glance to take out process memory area details using one adviser file format. My query is:

How to modify process id given in adviser file:

"if PROC_PROC_ID == 2244"

mean modifying process number (2244) using sed or tr?

[Hasan Atasoy]

hi ;

first create a template and put ZZZZ as process id in template file ;
second ,
tr -s "ZZZZ" processid < template_file > adviser file.

third ;
give adviser_file to glance,

I hope ıunderstand truely.

Hi,

the problem is ZZZZ will vary and have any process id to monitor. so, I am looking for command independent of existing process id in adviser file.

Hi,

if you insist in not using templates:

otherpid=4711
awk -v newid=$otherpid'"' '$2=="PROC_PROC_ID" {$4=newid; print}' adviser1 >adviser2

Hi"

Use Perl and you can update your adviser file "in place":

# perl -pi.old -e 'BEGIN{$pid=shift or die};s/(if PROC_PROC_ID\s*==\s*)(\d*)\b/\1$pid/' pid_value adviser

The original 'adviser' is retained as a backup called 'adviser.old'. No matter what the value of the pid in the string shown, it will be replaced with your value, passed as a first argument.

Thus in the example above, if you want a 'pid' value of 12345, pass that as the 'pid_value' and pass "adviser" (or whatever) as the filename.

Regards!
