Copy-From-File Script

A simple script to copy content from a file, specifying a starting and an ending line.

Requirements

1. Root privileges.

2. sed and xclip (and git if you want to clone the repo).

   The sed package is commonly pre-installed in the Linux distros.

   But xclip is not a package included by default.

Install sed and xclip:

In Debian-based:

sudo apt install sed xclip

With pacman (arch-based):

sudo pacman -S sed xclip

For Fedora:

sudo dnf install sed xclip

Now, if you have sed and xclip you can install the script.

Installation

Clone the repo and set up the script:

git clone https://github.com/FabrizioJordan/copyFromFile.git && cd copyFromFile

chmod +x copyFromFile && sudo cp copyFromFile /usr/local/bin

But if you want a shorter command, you can create a alias like cpff or cpFromFile.

Or you can run this command (to create a Symlink):

sudo ln -s /usr/local/bin/copyFromFile /usr/local/bin/cpff

How to update

Update is so easy

Now you have two options

Using an argument with the command -> Like this:

copyFromFile --update

From the terminal -> Only run this command:

git clone https://github.com/FabrizioJordan/copyFromFile.git && cd copyFromFile && sudo cp copyFromFile /usr/local/bin/copyFromFile && cd .. && rm -f copyFromFile

Usage

How this script works?

Its easy. You only need to pass three arguments.

1. The starting line.

2. The ending line.

3. The file name.

But you have two arguments:

1. -a | --all

   With this argument only pass the file.

2. -o | --one-line

   This argument needs the line to copy and the file.

Examples of use

This examples shows how this script can be used easilly:

This example copies the content from the line 10 to line 30 in file.txt file.

copyFromFile 10 30 file.txt

If you created an alias, you can use it in the same way:

cpff 10 30 file.txt

The next example copies all of the content from the file.txt file.

copyFromFile --all file.txt

Finally, the --one-line argument, this argument copies only one line from the file and is easy to use.

copyFromFile --one-line [Line] [File]

Example:

copyFromFile --one-line 5 file.txt

All arguments

-h | --help: Shows the help menu

-u | --update: Updates the program

-v | --version: Shows the actual version of the program

-a | --all: Copies all of the content from the file

-o | --one-line: Copies only one line from the file

Uninstallation

During installation, the script is copied to /usr/local/bin. If you wish to uninstall it, follow these steps:

To remove the script:

find /home/ -type f -name "copyFromFile" -exec rm {} \; && sudo find /usr/ -type f -name "copyFromFile" -exec rm {} \;

If you renamed the script during installation (e.g., to cpff):

find /home/ -type f -name "cpff" -exec rm {} \; && sudo find /usr/ -type f -name "cpff" -exec rm {} \;
