f Add flag at current address

Usage: f [?] [flagname] # Manage offset-name flags

Tips

- > To show all the contents of a flag space, use fs [space_name]; f

• f list flags (will only list flags from selected flagspaces)

  • To create a new flag, use f flag_name @ offset

  • To rename / substitute the value of an offset, use a . in the flag name. Example f some.flag=@0x00123456`

• f?flagname check if flag exists or not, See ?? and ?!
• f. [*[*]] list local per-function flags (*) as r2 commands
• f.blah=$$+12 set local function label named 'blah'
• f* list flags in r commands
• f name 12 @ 33 set flag 'name' with length 12 at offset 33
• f name = 33 alias for 'f name @ 33' or 'f name 1 33'
• f name 12 33 [cmt] same as above + optional comment
• f-.blah@fcn.foo delete local label from function at current seek (also f.-)
• f-- delete all flags and flagspaces (deinit)
• f+name 12 @ 33 like above but creates new one if doesnt exist
• f-name remove flag 'name'
• f-@addr remove flag at address expression
• f. fname list all local labels for the given function
• f= [glob] list range bars graphics with flag offsets and sizes
