Top Forums Shell Programming and Scripting randomly shuffle two text files the same way Post 302551840 by Corona688 on Wednesday 31st of August 2011 08:21:44 PM

Combine them into one line of two things with paste, shuffle them with shuf, separate them out into two files again. I've done it with awk but you could do it many ways.
Code:
$ paste -d : file1 file2 | shuf
five:5
two:2
one:1
four:4
three:3
$ paste -d ':' file1 file2 | shuf | awk -v FS=":" '{ print $1 > "out1" ; print $2 > "out2" }'

Your output files shouldn't be the same as your input files. If you need it to be, just rename the new files overtop of the old.

I didn't know about the shuf command. Thanks.

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
