[Solved] How to delete duplicate entries without using awk command?
Hello..
I am trying to remove the duplicate entries in a log files and used the the below shell script to do the same.
Code:
awk '!x[$0]++' <filename>
Can I do without using the awk command and the regex? I do not want to start the search from the beginning of the line in the log file as it contains date and time which of course varies from line to line. I am not able to write an effective script to do this functionality. Can anyone help me please?
