Function Run-Program

Part of:

package elprep
( run-program < command > < command-args > &key < input > < output > < error > (wait t) < if-input-does-not-exist > (if-output-exists error) (if-error-exists error) (external-format latin-1) )
A wrapper for sys:run-shell-command in LispWorks to make it behave more like SBCL's sb-ext:run-program.
