Find Duplicate Files (based on size first, then MD5 hash)

Count unique lines in file sorted by instance count (descending) and alphabetically (ascending)

I used to do this sorting with:

sort file.txt | uniq -c | sort -nr

But this would cause the line (2nd column) to be sorted in descending (reverse) order as well sa the 1st column. So this will ensure the 2nd column is in ascending alphabetical order.

Find Duplicate Files (based on size first, then MD5 hash)

This is a modified version of the OP, wrapped into a bash function.

This version handles newlines and other whitespace correctly, the original has problems with the thankfully rare case of newlines in the file names.

It also allows checking an arbitrary number of directories against each other, which is nice when the directories that you think might have duplicates don't have a convenient common ancestor directory.

find duplicate messages in a Maildir

# find assumes email files start with a number 1-9

# sed joins the lines starting with " " to the previous line

# gawk print the received and from lines

# sort according to the second field (received+from)

# uniq print the duplicated filename

# a message is viewed as duplicate if it is received at the same time as another message, and from the same person.

The command was intended to be run under cron. If run in a terminal, mutt can be used:

mutt -e "push otD~=xq" -f $folder
