Text processing#

Bash functions for text processing & strings.

implode#

Concatenate arguments using a specified joining character, similar to other programming languages. This can be useful to create, e.g. a comma-delimited list from an array of names.

Usage

Params:
CHAR               Joining character
ITEM               Strings to join

lines-dir#

Count total lines of all files in a directory. This function works well only with text files. If you're curious about how many lines of code are in that src/ dir...

Usage

lines-dir DIR [EXTRA]...

Params:
DIR                Directory to count
EXTRA              Optional extra params to 'find'

read-file-cfg#

Read a config file. Blank lines (consisting only of whitespace) and comments (lines starting with #) are removed. Sections are marked with square brackets, and you can choose to return all sections or just one. Content inside sections are returned unparsed, so format is up to you (square brackets: [, ] can't be used though).

Config file example:

# This is a comment

  # Whitespace allowed before comments
[section]
some options
format=no
which;is;best;suited
[other section]

Usage

read-file-cfg FILE [SECTION]

FILE               Config file to parse
SECTION            Optional section. If specified read only this section.
