This will extract the lines having strings with "mn" at end

and print the first word after first "=" sign (which is the second column with = sign as column separator)

example

if
ODBCHOME=/usr/damn/odbc is set in your .profile file

then it will display /usr/damn/odbc

Question

Thanks Karnan,

I've some more questions. Reqst you to answer these.
1) Why 'env' is used there?
2) This line of code is used in all the Control-M script, why they are searching for '..mn' (tow dot's).

Thanks in advance,
Lokesha

Java

Correct me if Iam wrong.

env will shows the environmental variable values, and from that output grep is searching for '..mn'.

With Regards,

env has the common path or other setting used by the scripts

two dots represents minimum 2 letters before mn [..mn]
