Creates a new bash script file in the current working directory. This is meant for #WSL users as it kind of solves the CR [Carriage Return (\r)] and LF [Linefeed (\n)] issue in Windows, since the file will be created in the Linux environment, and not Windows.

# Description : Short for 'Create Script File' [A simple bash script creator]
#               Creates a new bash script file in the current working directory.
#               This kind of solves the CR [Carriage Return (\r)] and LF [Linefeed (\n)] issue in Windows,
#               since the file will be created in a Unix environment, and not Windows.
#               Therefore, after creating the script file, just open it in your editor and start writing your script
# Options     : Specify file name [you can choose to add a bash extension]

### Prompt for file name
prompt() {
    read -r -p "File name(s) [Space or comma separated]: " file;
    echo "$file";
}


### Create a script file with argument as name,
### set execute permissions
### and add brief documentation
createScriptFile() {
    if [[ ! -e "$PWD/$1" ]];
    then
        touch "$PWD/$1"  # Create file
        chmod u+x ${1}   # Modify the file's permission

        # Adding some content to the newly created file
        printf "%s\n\n" "#!/bin/bash" > ${1}     # shebang!

        # A brief documentation
        printf "#: Title:           %s\n" "$1" | cat >> $1
        printf "#: Date:            %s\n" "$(date)" | cat >> $1

### If no argument is passed when script is invoked
if [[ $# == 0 ]];
then
    # Prompt for file name(s) and save input in array (names)
    IFS=', ' read -r -a names <<< $(prompt)
    for name in "${names[@]}"
    do
        createScriptFile ${name};
    done
    exit 0;

USAGE

• Create a bin directory in your home directory [ ~/bin ], if you don't already have it and export it to your PATH
  • Follow this tutorial on how to achieve this
• Save this script in the newly created bin directory. [ ~/bin/csf ]
  • You can copy and paste the code in the file or use wget.
• Make sure the script has executable permission. If not, set it using chmod u+x csf
• Creating script files with csf is easy.
  • csf filename creates a single script file
  • csf filename1 filename2 filename3 creates multiple files in the current working directory
  • csf will prompt user to enter file name(s).
