Need to Grep or awk a logfile for greater than value
Hello all
Hoping someone would be kind enough to suggest a solution to a problem i have, and see if maybe i can even do this without a script.
Essentially i have a very large log file, and within it each line had a value called TTMT, and it records a variable number in the following way, so if a message took 20 mseconds it would appear as TTMT {20} or 21 mseconds then TTMT {21}
There are thousands of entries of TTMT in this logfile and i am only concerned with timings above 20 mseconds, so would like to look only at message strings where the number is geater than 20, and append/write them to a seperate file.
I can do a
grep 'TTMT {21}' friday.log |more to see each message where its 21 but i would like a way to see anything above 20 and snend to another log > above20.log
I believe i could use awk but can not see a way to do this correctly, is it possible to do the above using awk or/and grep? rather than having to create a script?
Any advice gratefully accepted
