I want to create a zipped output file while keeping the original one. I want to do it from Informatica end by using command task or session task.

Below is the example which I am trying:

1. In session task: Command type='Command',
   Command=
   gzip -c /var/opt/powermart/pc8_dev/infa_shared/TgtFiles/test1/tgt_zip.out



2. 
   

   In case of using Command task:

   
   
   

   gzip -c /var/opt/powermart/pc8_dev/infa_shared/TgtFiles/test1/tgt_zip.out

   
   

I tried both things, but zip file is not at all created.

Below is the screen shot:

You can keep original file by using -c options and redirect output to another file:

gzip -c file > file.gz

It will keep your original file unchange and create its gzip file named file.gz

Your zip file isn't being created because the -c option for gzip means that the compressed file is sent to stdout instead of being written to disk. For what you want, you could either do what Laurent suggested in his comment, or you could use zip instead of gzip, which leaves the original files as well as creating a .zip file:

zip /var/opt/powermart/pc8_dev/infa_shared/TgtFiles/test1/tgt_zip.out.zip /var/opt/powermart/pc8_dev/infa_shared/TgtFiles/test1/tgt_zip.out

Or:

cd /var/opt/powermart/pc8_dev/infa_shared/TgtFiles/test1/ && zip tgt_zip tgt_zip

gzip -c reads a file (or standard input when file name is - ) and writes a compressed version to standard output.

So save contents to a new file then stdout redirection can be used.

gzip -c inputfile >outputfile

To simply compress in place and produce inputfile.gz

gzip inputfile

If informatica is ignoring the stdout redirection, you could pass the whole command to a shell (sh, csh, bash, ...) and let it do it instead,

Command=sh -c "gzip -c filename > newfilename"

I'm not an informatica user, so their forum for more information on that product here.

Here's a simple script to use from informatica which hides i/o redirection.

$ cat infagzip.sh 

#!/bin/sh



if [ $# -ne 2 ]

then

    echo "Usage $0 : inputfile outputfile "

    exit 1

fi

 gzip -c "$1" > "$2"

Now your Command line should look like this

/path/to/infagzip.sh inputfilename outputfilename
