Format
Description
Badly formed line/character count string
In an option of the form –n number or –number, the number was not a valid
number.
Reopening file descriptor number
–f was used to follow a file as it grew. tail closed the file associated with
the given file descriptor number and then tried to open it 2 seconds later. At
this point, tail found it could not reopen the file for reading, and therefore
could not follow the file any longer.
POSIX.2, X/Open Portability Guide, UNIX systems.
The POSIX standard does not include the use of b, k, or m as either options or
suffixes. –l is an extension of the traditional implementation of tail.
talk address [terminal]
