Randomize lines of a file 1

[ianicr]

Is there a command or script to randomize the lines of a file?

Thanks

One way...

awk 'BEGIN {srand}
{do x=rand; while(a[x]!="" a[x]=$0}
END {for(x in a) print a[x]}
' infile

Here's a Korn shell version...

#!/bin/ksh

typeset -RZ6 KEY

while read RECORD
do
        KEY=${RANDOM}
        print "${KEY}:${RECORD}"
done < file.orig | sort -n | sed 's/^[0-9]*://1' > file.unsorted

...where [tt]file.orig[/tt] and [tt]file.unsorted[/tt] are the input and output files.

Hope this helps.

Thanks for both. Used the awk one and it worked great!
