からman lsof
:
+c w defines the maximum number of initial characters of the name, supplied by the UNIX dialect, of the UNIX command associated with a process to be printed in the COMMAND column. (The lsof default is nine.) Note that many UNIX dialects do not supply all command name characters to lsof in the files and structures from which lsof obtains command name. Often dialects limit the number of characters supplied in those sources. For example, Linux 2.4.27 and Solaris 9 both limit command name length to 16 characters. If w is zero ('0'), all command characters supplied to lsof by the UNIX dialect will be printed. If w is less than the length of the column title, ``COMMAND'', it will be raised to that length.
