shell_sequencer

Shell script as wrapper for sequential tasks, such as complex server installations or recurring maintenance tasks.

The sequence script (seq) containing different steps is separated from the sequence control (sequencer.sh). The seq just needs to "include" the sequencer.sh at the end.

sequencer.sh

Main sequencer script to be included at the end of a seq.

seqs/

Contains sequences (seqs) for different tools, servers or occasions.

Sequencer include working on sh and bash.

[...]
. /usr/local/bin/sequencer.sh

see seqTemplateExample.sh (which can be generated when calling sequencer.sh directly)

Installation recommendation

To make all seqs avaialable to all user, follow the procedure below.

Run folloing commands as root:

git clone https://winklerfamilie.eu/git/efelon/shell_sequencer.git /opt/sequencer
ln -s /opt/sequencer/sequencer/sequencer.sh /usr/local/bin
ln -s /opt/sequencer/seqs /opt

or

use the simple bash installation script in the repository:

curl -L https://winklerfamilie.eu/git/efelon/shell_sequencer/raw/branch/master/install.sh | bash

Bash-completion

The included optional bash-completion script sqnall-completion.bash provides aliases to all available sequences as well as completion for sequencer.sh options and steps (including aliases) individually for each sequence. The aliases have the prefix sqn_ which stands for sequence name.

After executing

source /opt/sequencer/sqnall-completion.bash

e.g. /opt/sequencer/seqs/kodi.sh can be started anyhere with sqn_kodi

Automatic setup after login

To automatically provide aliases and bash-completion after login, the following bash script needs to be executed once for each user separately:

source /opt/sequencer/installCompletion.sh

This sources the bash-completion script in the users .bashrc file.
