The OVYA Library Bash Shell Function (ol-bash) is a small bash script that
acts as a library for bash scripts. It provides a couple of functions
that makes the lives of most people using shell scripts a bit easier.
This project is a fork of the original work of Louwrentius.
In order to use ol-bash, you have to include the library in your bash
scripts. You can do it with an absolute path :
source <absolute path to `ol-bash`>
For example :
source /opt/lib/ol-bash.sh
Or with a relative path :
declare -r DIR=$(cd "$(dirname "$0")" && pwd)
source $DIR/<relative path to ol-bash>
The best way to learn how ol-bash works is to look at the examples
available in the examples folder.
The online documentation is available here.
Building the documentation is done by using Doxygen :
cd <ol-bash repository>/doc
doxygen Doxyfile
or
cd <ol-bash repository>
make doc
BSFL is implemented for bash version 4. Prior versions of bash will fail at interpreting its code.
In addition, ol-bash depends of some external programs. Here is the list
of these programs :
- tr
- logger
- date
- tput
- grep
- printf
- sed
- getent
- read
However, we try to get as much as possible a standalone library. Hence, some of these external dependencies will be removed in the future.
ol-bash uses Bats testing framework to verify the correct behaviour
of its functions.
To run all the tests :
bats <ol-bash repository>/test
or
cd <ol-bash repository>
make test
To run only the tests of a specific group :
bats <ol-bash repository>/test/<test file>
For example, for the network group :
bats <ol-bash repository>/test/network.bats
This project is still under development. Contributions are welcomed.
