Unix Script

Hi,

I need a unix script which can take as input a list of invoice numbers in a text file and do a search in a particular directory and find the file containing that invoice number.

It should then copy this particular file found into a different directory. Please note I only need to copy this file to a different directory and not move it.

So if there are 100 invoice numbers in the text file then this script should be able to copy 100 files to the destination directory. I can enter the invoice numbers in the text file in any manner.

Thanks for your help.

Regards
Pradeep

Something like this:

cat $1 | while read invoiceno
do
  for ffound in `grep -l -R ${invoiceno} *`
  do
  echo cp \"${ffound}\" $2
  done;
done;

Open in new window

Put the above in a script file, call it like this:

sh script.sh files.txt /var/tmp

Where files.txt contains one invoicenumber per line and /var/tmp is your output folder. Note the echo before the copy command, the script will show you what it would to. Remove the echo to make the copy.

Hi Gerwin,

I would also like to specify the directory where the files should be searched. As I understand /var/tmp is the path where files will be copied. Where do I put the path where the files should be searched for the invoice numbers?

Extra parameter:
cat $1 | while read invoiceno
do
  for ffound in `grep -l -R ${invoiceno} $2/*`
  do
  echo cp \"${ffound}\" $3
  done;
done;

Open in new window

Call like this:

sh script.sh files.txt /path/to/source /var/tmp

#! /bin/sh
cd $2
while read invoiceno
do
  if [ -e "$invoiceno" ]
  then
    cp $invoiceno $3
  fi
done < $1

or

#! /bin/sh
cd $2
for invoiceno in `cat $1`
do
  if [ -e "$invoiceno" ]
  then
    cp $invoiceno $3
  fi
done

Hi Gerwin,

Is it possible to keep the"echo" and just pipe the output into a file that you can use as "copy-script" afterwards. Then I will also have a chance to review before copying.

How to achieve this?

Hello Pradeep, of course, just redirect the output of the script to a file, in general, like this:

script > outputfile

So in your case:

sh script.sh files.txt /path/to/source /var/tmp > copy_script

This way the script.sh creates an output file (copy_script) that you can use later or as a reference.

If you would run the script and collect 'error' output, you can direct to a second file, like this:

sh script.sh files.txt /path/to/source /var/tmp > copy_script 2>error_output
