NAME¶
tail - output the last part of filesSYNOPSIS¶
tail [ OPTION]... [FILE]...DESCRIPTION¶
Print the last 10 lines of each FILE to standard output. With more than one FILE, precede each with a header giving the file name. With no FILE, or when FILE is -, read standard input. Mandatory arguments to long options are mandatory for short options too.- -c, --bytes=K
- output the last K bytes; or use -c +K to output bytes starting with the Kth of each file
- -f, --follow[={name|descriptor}]
- output appended data as the file grows;
- an absent option argument means 'descriptor'
- -F
- same as --follow=name --retry
- -n, --lines=K
- output the last K lines, instead of the last 10; or use -n +K to output starting with the Kth
- --max-unchanged-stats=N
- with --follow=name, reopen a FILE which has not
- changed size after N (default 5) iterations to see if it has been unlinked or renamed (this is the usual case of rotated log files); with inotify, this option is rarely useful
- --pid=PID
- with -f, terminate after process ID, PID dies
- -q, --quiet, --silent
- never output headers giving file names
- --retry
- keep trying to open a file if it is inaccessible
- -s, --sleep-interval=N
- with -f, sleep for approximately N seconds (default 1.0) between iterations; with inotify and --pid=P, check process P at least once every N seconds
- -v, --verbose
- always output headers giving file names
- --help
- display this help and exit
- --version
- output version information and exit
