Korn Shell Scripting problem

Jeremy_5 — Tue, 20 Mar 2001 16:45:51 GMT

Hello All-

I need a line to add to the following shell script that will rename files from this format

JJONES.12345
THONEYCUTT.44332
RCRASUS.55555

to this format

12345.pdf
44332.pdf
55555.pdf

respectively.

Basically dropping the original alphabetic prefix, making the numeric extension the new prefix, and adding a .pdf extension. This is not a conversion job, just a renaming.

The original filenames are passed to the script in variable format by an oracle application. The file needs to be renamed before it is copied to it's destination (invoice_in)

Any help on this issue would be greatly appreciated!

--BEGIN KORN SHELL SCRIPT--

#!/usr/bin/ksh
# A simple script to copy a file submited to invoicetopdf to the invoice_in
# directory. It takes the first positional parameter as its only argument.

echo "I am in the script" >> /tmp/inv.err
echo $# >> /tmp/inv.err
echo $* >> /tmp/inv.err
echo "File name is: $1" >> /tmp/inv.err
cp $1 $APPL_TOP/ecan/invoice_in/in/ >> /tmp/inv.err
print $? >> /tmp/inv.err

--END OF SCRIPT--

Thanks-Jeremy

Your processing loop should be something like:-

for FILE in ${*}
do
SUFFIX=${FILE#*.} # leave chars after final .
cp (or mv) ${FILE} /${SUFFIX}.pdf
done

newnam="${file##*.}.pdf"
mv $file $newname

You could also use the cut feature:

var1="`echo $1 | cut -d. -f2`.pdf"
mv $1 $var1

filename=$(cat $yourfilename | sed -n 's|^[A-Z]*\.$[0-9]*$$|\1.pdf|p)
if [[ -z $filename ]] ;then
invalid file name message
exit
fi

Unless you know for sure that each numeric suffix of the old filename will be unique from any other suffix, I would also add code to check for the existance of the new filename before you write it. Otherwise you may end up overwriting other output.

a million ways to skin a cat.

newfile=`echo $file | awk -F \. '{print $2}'`.pdf
mv $file $newfile
