in reply to is this correct

What's append if the file take 150mb of disk space ?

Maybe you may use something like this :

# perl -e 'while(<>){s/\t/ /g;print}' < file > file.tmp;\ > mv file.tmp file;

Update : Thank's arhuman for this comment. This option is really usefull.

Hope this helps

    In case like this (a while loop around one or more files) the perl -ne is usually a good candidate...

    Something like :
    perl -ne 's/\t/ /g;print' file > file.tmp; mv file.tmp file;
      To abstract it a little more

      perl -i.back -pe 's/\t/    /g' file

      The -i means copy original file to file.back and put the output of program in file. The -p is like -n but does while(<>){YOUR_CODE; print;} instead.
