Tail

O que faz?

Comando do terminal Linux que retorna o final de um arquivo.

Sintaxe

tail [OPTION]... [FILE]...

Opções

• -c, --bytes=[+]NUM: output the last NUM bytes; or use -c +NUM to output starting with byte NUM of each file

• -f, --follow[={name|descriptor}]: output appended data as the file grows;an absent option argument means 'descriptor'

• -F: o mesmo que --follow=name --retry

• -n, --lines=[+]NUM: output the last NUM lines, instead of the last 10; or use -n +NUM to output starting with line NUM

• --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.

• -z, --zero-terminated: line delimiter is NUL, not newline

• --help: display this help and exit

• --version: output version information and exit
