shtk_cleanup_register —
Installs cleanup handlers to be called on script
termination
shtk_import cleanup
shtk_cleanup_register |
handler1 [.. handlerN] |
The shtk_cleanup_register function
installs one or more cleanup handlers, given in the
handler1 to handlerN arguments
as function names.
The registered handlers are executed in the order they are originally registered. Registration of handlers is idempotent.
The following example creates a temporary file and installs a cleanup handler to ensure that the file gets removed when the script terminates:
local pattern="${TMPDIR:-/tmp}/my_program.XXXXXX"
local temp_file="$(mktemp "${pattern}" 2>/dev/null)"
[ -f "${temp_file}" ] || shtk_cli_error "Failed to create temporary file"
eval "remove_temp_file() { rm -f '${temp_file}'; }"
shtk_cleanup_register remove_temp_file
shtk_cleanup_register first appeared in
shtk 1.4.
