Hi,

Need help in Parametrize the file name and passing the file name as a prompt to the script.

Currently I am using a filename inside my script has below

Code:

export input_filename=/path/SRC_FILE_NAME.txt

I want to parametrize the filename and pass SRC_FILE_NAME.txt to the shell script as below to make the filename as dynamic

Code:

sh shellsctipt.sh SRC_FILE_NAME.txt

Please tell me how can I do this.

Regards, Deepti

Hi,

I have gone through the link and applied in my sed command but the argument is not working.

I am trying to modify an existing shell script which is doing etl validations.
below is the sed command where filename is hardcoded

Code:

sed 's/[^|]//g' /tmp/test/sample.txt

I have defined a parameter in the beginning of the shell script as
Filename=$1

And modified the sed command as below

Code:

sed 's/[^|]//g' /tmp/test/${"1"}

And passed the filename to the shell script as validate.sh sample.txt

but the argument is not working.

Please let me know if I am missing anything.

Regards,Gaur

Remove that double quotes around 1:

Code:

sed 's/[^|]//g' "/tmp/test/${1}"

OR if you have assigned first argument to variable:- Filename:

Code:

sed 's/[^|]//g' "/tmp/test/${Filename}"
