Top Forums Shell Programming and Scripting Script to compare files in 2 folders and delete the large file Post 302999856 by Josh52180 on Wednesday 28th of June 2017 07:21:54 PM

I searched many forums before deciding to join here. I usually find a solution but this one has proven to be hard to find.

If the answer has already been posted I apologize for creating another post about it.

I am running Ubuntu 17.04 Server on my encoding machine which sits in my basement and I access it through SSH. I am thinking of utilizing diff along with a bash script to determine whether the original or re-encoded file is smaller and then have it delete the larger of the 2 files.

I got as far as playing around with diff a little bit but I am not a script writer so I have no idea how to implement what I want to do into an efficient script.

I will try searching the forum again.

NAME
diff - print differences between two files SYNOPSIS
diff [-c | -e | -C n] [-br]file1 file2 OPTIONS
-C n Produce output that contains n lines of context -b Ignore white space when comparing -c Produce output that contains three lines of context -e Produce an ed-script to convert file1 into file2 -r Apply diff recursively to files and directories of EXAMPLES
diff file1 file2 # Print differences between 2 files diff -C 0 file1 file2 # Same as above diff -C 3 file1 file2 # Output three lines of context with every diff -c file1 file2 # Same diff /etc /dev # Compares recursively the directories /etc and /dev diff passwd /etc # Compares ./passwd to /etc/passwd DESCRIPTION
the same name, when file1 and file2 are both directories" difference encountered" Diff compares two files and generates a list of lines telling how the two files differ. Lines may not be longer than 128 characters. If the two arguments on the command line are both directories, diff recursively steps through all subdirectories comparing files of the same name. If a file name is found only in one directory, a diagnostic message is written to stdout. A file that is of either block special, character special or FIFO special type, cannot be compared to any other file. On the other hand, if there is one directory and one file given on the command line, diff tries to compare the file with the same name as file in the directory directory. SEE ALSO
cdiff(1), cmp(1), comm(1), patch(1). DIFF(1)
