Create listreqs bash/shell script

[Mr-Destructive]

Addressing the Issue #1

Added a shell script that converts an requirements.txt file from a list format to a freeze format that can be in a downloadable format for pip.

Below is a quick demonstration.

Usage:

1. Can pass in as a positional(command line) argument:

bash listreqs.sh reqs.txt

2. Can input the file name from the prompt after running the shell script

bash listreqs.sh
Enter the requirements file name : reqs.txt

3. Not passing any input will lead to the creation of a default file called requirements.txt.

bash listreqs.sh
Enter the requirements file name :

Its LGTM, just one thing though
As mentioned in the issue to perform both the steps pip list > reqs.txt and python script into a single step, for doing that I guess you need to add the pip list > reqs.txt inside the shell script that you have written.

Rest is great. Thank you.

@Mr-Destructive can you please check, if the code is running or not, its not running for me.
sed: can't read requirements.txt: No such file or directory

What were the inputs for the script?

[soumya997]

It was showing Enter the requirements file name : so I gave a name for the file like requirements.txt. Thats the input.

And also even if I create the file and then give the created file name as the input . It does not throw any error but the after running the shell script the created file is empty.

[Mr-Destructive]

Is it now fine? I assumed the file was already created. Thanks for the feedback 👍
