multitail [-cs|-Cs|-c-] [-i] inputfile [-i anotherinputfile] [...]
-i x the following parameter is a filename (in case it starts with a dash)
-I x like -i only this one merges this logfile into the previous window
-l x parameter is a command to be executed
-L x see -l but add to the previous window
-j read from stdin (can be used (of course) only once)
-J like -j but merge into previous window
--listen [interface]:port behave like a syslog server. port is normally 514
--Listen [interface]:port like --listen but merge into previous window
-r interval restart the command when it died after `interval' seconds
-R interval same as -r, only with this one only the difference is displayed
-Rc/-rc interval like -r/-R but clean the window before each iteration
--cont reconnect lines with a '' at the end
--mergeall merge all of the following files into the same window (in the previous window)
--mergeall-new merge all of the following files into the same window (in a new window)
--no-mergeall stop merging all files into one window
--no-repeat suppress repeating lines and replace them with a "last message repeated x times"
--mark-interval x when nothing comes in, print a '---mark---' line every 'x' seconds
--mark-change when multiple files are merged an multitail switches between two windows, print a markerline with the filename
--no-mark-change do NOT print the markerline when the file changes (overrides the configfile)
-n x initial number of lines to tail
-m x set scrollback buffer size (# lines)
-mb x set scrollback buffer size (in bytes, use xKB/MB/GB)
-bw a/f what to buffer: 'a'll or what went through the 'f'ilter
-a x like 'tee': write (filtered) input to file 'x'
-A x see -a: but write the unfiltered(!) input to file 'x'
-g x redirect the input also (filtered) to command/process 'x'
-G x redirect the unfiltered input also to command/process 'x'
--label x put in front of each line
-q i path check every 'i' seconds for new files in 'path', create a new window for those
-Q i path check every 'i' seconds for new files in 'path', put them all in the same window (using subwindows)
--closeidle x close windows when more then 'x' seconds no new data was processed
--new-only (for -q/-Q) only create windows for files created after multitail was started
-s x vertical split screen (in 'x' columns)
-sw x,x,... at what columns to split the screen, use '0' for automatic size
-sn x,x,... number of windows per column
-wh x height of window
-S prepend merged output with subwindow-number
-f follow the following filename, not the descriptor
--follow-all for all files after this switch; follow the filename instead of the descriptor
--retry keep trying to open the following file if it is inaccessible
--retry-all like --retry but for all following files
-fr scheme use the predefined filter from the configfile
-e[m] print only when matching with this regexp
-ev print only when NOT matching with this regexp
-ec use regular expression but display the matches inverted on following file
-eC use regexp, display everything but matches inverted on following file
-ex execute command ('-ex regexp command') when matches, matching line is given as commandline parameter
-eX like -ex but only give the matching substring as commandline parameter to the command
-E use regular expression on following files
-Ec use regular expression but display the matches inverted on following files
-EC use regexp, display everything but matches inverted on following files
-ke x strip parts of the input using regular expression 'x'
-kr x y strip parts of the input starting at offset x and ending (not including!) offset y
-kc x y strip parts of the input: strip column 'y' with delimiter 'x'
-ks x use edit scheme 'x' (defined in configfile)
-kS x only show the substrings matched by the substring-selects (the parts between '(' and ')') in the regular epxression 'x'
-v invert next regular expression (do not use with -ev/em)
-cv x use conversion scheme 'x' (see multitail.conf)
-c colorize current
-cS scheme use colorscheme 'scheme' (as defined in multitail.conf)
-csn extra switch for the following switches; do not use reverse (inverted) colors
-Cs colorize all following files with syslog-scheme
-C colorize all following files
-Cf/-cf field delimiter colorize next/all file(s) depending on the given field number. fields are delimited with the given field-delimiter
-ci color use 'color' (red, green, etc), usefull when merging multiple inputs
-c- do NOT colorize the following file
-C- do NOT colorize the following files
-cT term interpret terminal-codes from file/command (for terminal type 'term')
-Z color set color for markerline
-ts add a timestamp (format configurable in multitail.conf) before each line
-T put a timestamp in markerlines
-d do NOT update the status-line
-D do not display a status-line at all
-du put the statusline above the data window
-z do not "window closed" windows
-w do not use colors
-u set update interval (for slow links)
-p x [y] set linewrap (l=left/a=all/r=right/s=syslog,S=syslog w/o procname,o=offset -> 'y',w=wordwrap)
-P like -p but for all following files
-b n set TAB-width
--basename only display the filename (and not the path) in the statusline
-x str switch on the xtermtitlebar stuff
-F file use 'file' as configfile (instead of //etc/multitail.conf)
--no-load-global-config do not read //etc/multitail.conf
-o configfileparameter do a setting which would normally be set in the configfile
-H x show heartbeat (to keep your sessions alive)
-iw file i check every 'i' seconds if 'file' appeared in the filesystem
-t x display 'x' in the window-title (when MultiTail runs in an xterm)
--beep-interval x beep every x lines processed
--bi x like '--beep-interval' but only for current (sub-)window
-V show version and exit
-h this help
You can have multiple regular expressions per file/command. Be warned: if
you define multiple and one of them is specified with '-E' (=for every
following file), _all_ of the current regular expressions are for all
following files!
