Re: Re: is this correct

[arhuman]

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;

[repson]

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.
