Copy ????.ABC ????BCD

I'm looking for a shell script that will duplicate the Windows DOS bulk copy command, the title of this thread.

Anyone have one handy ??

Shalom Vernon,

ls -1 ????.ABC > list

while read -r filename
do
cp $filename ????BCD
done < list

For tasks like this I use the famous rename perl script (written by Larry Wall iirc). The rename script is (I hope this pastes ok):

#!/usr/bin/perl
#
# use shift to extract the first command line argument - this is the string
# containing the Perl statement(s) to be compiled and executed.
# These Perl operations are stored in a $op variable.

($op = shift) || die "Usage: rename expr [files]\n";

chomp(@ARGV = ) unless @ARGV;

foreach (@ARGV) {
# save the current file name in $was
$was = $_; # $_ is the default loop variable
eval $op; # compile and execute the Perl
# operations submitted by the user
die if $@; # means eval 'failed'
rename($was, $_) unless $was eq $_; # rename is a Perl built-in function
}

Then you use it like this:

rename 's/\.ABC$/BCD/' *.ABC

or maybe you meant:

rename.pl 's/\.ABC$/\.BCD/' *.ABC

HTH,
Ross

Shalom Vernon,

Sorry for the confusion.

thats supposed to be a dash one

-1

What dash one does is create a file list one file per line.

Its possible under certain circumstances at least under hpux to get two files on the same line. dash one prevents that.

I didn't realize with browser fonts and such I needed to clarify its not a dash el.

Hi SEP;

I tried the script, but would up with the actual ????.EXT question marks in the file name.
code:
unzip ???????k.zip
ls ???????.DRF > list
while read -r filename
do
cp $filename ???????.STK
done < list

Wound up with a file ???????.STK. I'm looking for LAD1117.STK. ( converting horse racing data files from DRF to STK file extension)

Thanks for your help. Still needs work :o)

Tried a variation:
code:
unzip ???????k.zip
ls ???????.DRF > list
while read -r filename
do
cp $filename $filename.STK
done < list

Wound up with: LAD1117.DRF.STK

Closer but now I need to strip the .DRF; maybe there's a way to strip $filename to the first seven characters; that would do it.

Hi,

if it is just a mattter of shortening "filename", you could try a small change like this:

.....
while read -r filename
do
#insert cut of filename
if [ "${#filename}" -gt 7 ]
then
filename=$(echo "$filename" | cut -c1-7)
fi
# insert end
cp "$filename" "$filename.STK"
done < list

regards,
John K.
