Removing Duplicate Lines With Sort, Uniq and Shell Pipes Use the following syntax: sort {file-name} | uniq -u sort file.log | uniq -u Unix: removing duplicate lines without sorting The UNIX Bash Scripting blog suggests: awk ' !x[$0]++' This command is simply telling awk which lines to print. The variable $0 holds the entire contents of a line and square brackets are array access. So, for each line of the file, the node of the array named x is incremented and the line printed if the content of that node was not (!) previously set. |
