Is there an option in textto not to change the file time when running
with -l and -c options?

No, but you could use the ‘touch’ utility to restore it.

I don’t think there is.

You can write a convoluted script that:

  1. copies a file to a new temp.name
    cat old.file | textto > temp.name
  2. touches the new file with the old date/time stamp
    touch -t find . -name old.file -printf "%TY%Tm%Td%TH%TM" temp.name
  3. and replaces the original file
    rm old.file
    mv temp.name old.file

Wouldn’t it be simpler to…

cp oldfile newfile
textto newfile
touch -r oldfile newfile
mv newfile oldfile

Actually, since the QNX version of cp preserves the original file time,
you could also do:

cp oldfile tempfile
textto oldfile
touch -r tempfile oldfile
rm tempfile

I did not know about the -r option to touch.

Thank you.

That’s the ticket. Come to think of it, no reason to actually copy the
data…


touch -r oldfile tempfile
textto oldfile
touch -r tempfile oldfile
rm tempfile

Never enough optimization!

Never enough optimization!

Every program has at least one bug.
Every program can be reduced by at least one line.
Therefore, every program can be reduced to one line that doesn’t work.
