| |
Hello,
I've just read Documentation/dynamic-debug-howto.txt (again) and I wonder what the parameter -c for echo is for (found at lines 94 ff).
Neither echo from coreutils nor the buildin from bash do know the parameter -c.
The paragraph which made me curious starts with
----- Command Language Reference ==========================
At the lexical level, a command comprises a sequence of words separated by spaces or tabs. So these are all equivalent:
nullarbor:~ # echo -c 'file svcsock.c line 1603 +p' > <debugfs>/dynamic_debug/control nullarbor:~ # echo -c ' file svcsock.c line 1603 +p ' > <debugfs>/dynamic_debug/control nullarbor:~ # echo -n 'file svcsock.c line 1603 +p' > <debugfs>/dynamic_debug/control -----
Is that -c a parameter for a buildin echo of one of the various shells, a typo (looks unlikely) or do I miss something else which make me look a noob?
Regards,
Alexander Holler
