concat.sh

concat.sh is a bash script that allows you to concatenate text files from a directory into a single output file. It provides several options to control the inclusion and exclusion of files, line filtering, and output file management.

Features

• Concatenate all text files from a directory into a single output file.
• Exclude specific files or directories from being processed.
• Skip empty files during the concatenation process.
• Filter lines in the files using a regular expression pattern.
• Easily specify the input directory and output file.

Installation

1. Clone this repository to your local machine:

   git clone https://github.com/yourusername/concat.sh.git

2. Navigate to the directory:

   cd concat.sh

3. Make the script executable:

   chmod +x concat.sh

Usage

./concat.sh [OPTIONS]

Options:

• -i, --input DIR
  Specify the input directory (default: current directory).

• -o, --output FILE
  Specify the output file (default: res.txt in the current directory).

• -s, --skipEmpty
  Skip empty files after processing.

• -e, --exclude DIR
  Exclude specified directories or files (can be used multiple times).

• -er, --excludeRegex REGEX
  Exclude lines matching the given regex pattern.

• -h, --help
  Show this help message and exit.

Examples:

1. Concatenate files, excluding empty files, directories, and using regex:

   ./concat.sh -i ./somePath -o output.txt -s -e ./dist ./node_modules -er '^import .*;'

   This will concatenate all files in somePath, excluding empty files, dist, and node_modules, removing lines starting with import, and write the output to output.txt.

2. Concatenate files from a log directory, skipping empty files and removing lines containing "DEBUG":

   ./concat.sh -i ./logs -s -er 'DEBUG'

   This will concatenate all files in the logs directory, skip empty files, and remove lines containing the string "DEBUG".
