At the start of the script, you define four variables (although one, SRCMAN_BASHRC
, is never used). Based on their usage, and the fact that they're uppercase, it seems as though you may be intending to read them from the environment.
Compare SRCMAN_SHELL=zsh
to SRCMAN_SHELL="${SRCMAN_SHELL:-zsh}"
. The former assigns a value. The latter assigns either the value of a variable or a default value (if the variable is unset). The fact the two variables are the same in this example is coincidental. See this page for more information on parameter expansion.
Using environment variables allows the script to be changed at runtime rather than needing to be modified. For example, SRCMAN_SHELL=zsh ./srcman
or SRCMAN_SHELL=bash ./srcman
