It does this because the gdb completion function is expecting just the program name (it automatically prepends the path), and using a subshell confuses awk. If you are going to use gdb completion, do not use a subshell and which, but rather (to follow your example): gdb somea<TAB> co<TAB> In order for the executable to be in gdb's completion list it would need to be executable and in the current path (same requirements for which).
