Sort all the ".dat" files in current directory by column 3 (change it accordingly), and replace the sorted one with original.

for x in *.dat;do sort -k 3 $x >tmp && mv -f tmp $x;done
We normally get tasks in which one has to sort a data file according to some column. For a single file say foo, we would use sort -k 3 foo >tmp && tmp foo The for loop is useful when we have to do it on a number of files.

What Others Think

You can use "-o" option of "sort" command to replace file directly, without using a temporary file. For a single file is: sort -k 3 -o foo foo
