dr_symlinks
dr_symlinks(1) USER COMMANDS dr_symlinks(1)
NAME
dr_symlinks - maintain a symlink forest
SYNOPSIS
dr_symlinks
DESCRIPTION
For each pair directory/subdirectory under each word in DR_SL_TARGETS, a directory and symlink DR_SL_SOURCE/directory/symlink is created (or
adjusted). The script is implemented as a wrapper around oggsymlinks, by Wessel Dankers.
EXAMPLE
If, in the configuration file $HOME/.draai/symlinksrc, DR_SL_SOURCE is set to /srv/audio and DR_SL_TARGETS is set to "../data/a ../data/b",
while directories
/srv/data/a/And_You_Will_Know_Us_By_the_Trail_of_Dead/Source_Tags_And_Codes/
/srv/data/a/And_You_Will_Know_Us_By_the_Trail_of_Dead/The_Century_of_Self/
/srv/data/a/John_Coltrane/A_Love_Supreme/
/srv/data/b/John_Coltrane/Giant_Steps/
/srv/data/b/Tinariwen/Amassakoul/
exist, the following directories holding the following symlinks will get created in /srv/audio/ :
And_You_Will_Know_Us_By_the_Trail_of_Dead/Source_Tags_And_Codes ->
../../../a/And_You_Will_Know_Us_By_the_Trail_of_Dead/Source_Tags_And_Codes/
And_You_Will_Know_Us_By_the_Trail_of_Dead/The_Century_of_Self ->
../../../a/And_You_Will_Know_Us_By_the_Trail_of_Dead/The_Century_of_Self/
John_Coltrane/A_Love_Supreme -> ../../../a/John_Coltrane/A_Love_Supreme/
John_Coltrane/Giant_Steps -> ../../../b/John_Coltrane/Giant_Steps/
Tinariwen/Amassakoul -> ../../../b/Tinariwen/Amassakoul/
All dangling symlinks and empty directories (if any) under /srv/audio/ will get removed. This script is idempotent.

ENVIRONMENT
dr_symlinks honors booleans: DR_SL_VERBOSE, DR_DEBUG and DR_DRYRUN and strings: DR_SL_RCFILE, DR_SL_TARGETS and DR_SL_SOURCE.
FILES, CONFIGURATION
All configuration variables (see ENVIRONMENT) can be set in ~/.draai/symlinksrc. This rc-file is sourced as a shell script. If DR_SL_RCFILE
is set, its value is assumed to be the dr_symlinks rc-file.
