Hello everybody,

I am a new user and pretty new at Linux.

I am looking for a script that i will enter him a path for LOG file, on this log file he will search for about 50-100 error codes that i will configure in the script.
And in the end it will output me the error codes that were find on the log file

And this script needs to be run on real time when log is updated (Shift+F)

For example:

code=202
code=205
code=300
code=122

script runs log file, ending output:
The code that were found are:
code=202
code=205

meaning, these are the codes that were found.

I hope its clear and understandable i have read a little bit on grap commend and tried to find information without success.

Thanks a lot.

What did you not understand about grep? You can either cycle through a file and grep for each individual line in the log file or if the codes are kept in a single file you can also
use the '-f' option to use the file as what grep needs to search for. Have a look at the man page as it is relatively easy to follow.
