When you compare two computer files on Linux, the difference between their contents is called a diff. Now we want to know the difference between the directories d1 and d2 and in order to print the difference we can make use of the command shown below − diff -q d1 d2 | cut -f2 -d ',' Output Only in d1: 1.txtĪnother command that we can make use of is also shown below − diff -qr d1 d2 Output Only in d1: 1.While writing program files or normal text files, programmers and writers sometimes want to know the difference between two files or two versions of the same file. rw-r-r- 1 immukul staff 0 Jul 5 20:03 2.txt Now the contents of the first directory d2 looks something like this − d2 % ls -ltr rw-r-r- 1 immukul staff 0 Jul 5 20:03 5.txt rw-r-r- 1 immukul staff 0 Jul 5 20:03 3.txt rw-r-r- 1 immukul staff 0 Jul 5 20:03 1.txt Now the contents of the first directory d1 looks something like this − d1 % ls -ltr Let’s explore the case where we have two directories d1 and d2 and both these directories contain some files in them.Ĭonsider the terminal output to depict these two directories shown below − linux-questions-code % ls -ltrĭrwxr-xr-x 5 immukul staff 160 Jul 5 20:03 d1ĭrwxr-xr-x 4 immukul staff 128 Jul 5 20:03 d2 This command is used to find the difference between two files as it compares both the files line by line.
