apropos args The apropos args command searches through all of the GDB

specified in args. It prints out all matches found. For example:
apropos reload

set symbol-reloading -- Set dynamic symbol table
reloading

show symbol-reloading -- Show dynamic symbol table
reloading

for the beginning of a command. Use args to specify the
beginning of the command you want completed. For example:
complete i
results in:
if
ignore
info
inspect
