Shell Programming and Scripting

Hi,

I have below lines in the log file. how to segregate and assign '3904' to a variable.

Code:

XCMM018I  Return Code: 8  Feedback: 0
          :&PNUM=3904:

Code:

$ awk '/NUM/{gsub("[A-Za-z:&=]","");print}' input.txt
3904

You could try the clumsy cut:-

Code:

string=":&PNUM=3904:"
my_var="`echo $string | cut -f2 -d= | cut -f1 -d:`"

... or if you have ksh installed, you could:-

Code:

#!/bin/ksh
string=":&PNUM=3904:"
my_temp_var="${string#*=}"
my_var="${string%:}"

You could also use tr to get rid of non-numerics like this:-

Code:

string=":&PNUM=3904:"
my_var="`echo $string | tr -d [a-zA-Z&=:]`"

I hope that these help, and you may get other suggestions.

To assign 3904 to a variable, use the following:

Code:

variable=3904

If you want to recognize 3904 in your log file and also recognize other values in your log file, you need to give us more information about how to determine what value(s) you want and how to recognize them.

Are you looking for any string of 4 digits that does not immediately follow an alphabetic character?

Are you looking for any string of digits following an equal sign character?

Are you looking for a number following &PNUM=?

If there is more than one string of digits that meets your criteria, do you want the first one, the last one, all of them, etc.?
