Use: jiofsck [clean=1] [dir=DIR] FILE\n\

Where \"FILE\" is the name of the file you want to check the journal from,\n\
and the optional parameter \"clean\" makes jiofsck to clean up the journal\n\
after recovery.\n\
The parameter \"dir=DIR\", also optional, is used to indicate the position\n\

Examples:\n\
# jiofsck file\n\
# jiofsck clean=1 file\n\
# jiofsck dir=/tmp/journal file\n\
# jiofsck clean=1 dir=/tmp/journal file\n\
