If it has +been replaced with other messages, look at /var/run/dmesg.boot. + -- Francisco Reyes <lists@natserv.com> +% +Want colour in your directory listings? Use "ls -G". "ls -F" is also useful, +and they can be combined as "ls -FG". +% +Want to find a specific port, just type the following under /usr/ports +or one its subdirectories: + + make search name=<port-name> + or + make search key=<keyword> +% +Want to know how many words, lines, or bytes are contained in a file? Type +"wc filename". + -- Dru <genesis@istar.ca> +% +Want to see how much virtual memory you're using?

Well, to replace every 'e' with +an 'o', in a file named 'foo', you can do: + + sed -i.bak s/e/o/g foo + +And you'll get a backup of the original in a file named 'foo.bak', but if you +want no backup: + + sed -i '' s/e/o/g foo +% +When you've made modifications to a file in vi(1) and then find that +you can't write it, type ``<ESC>!rm -f %'' then ``:w!'' to force the +write + +This won't work if you don't have write permissions to the directory +and probably won't be suitable if you're editing through a symbolic link. +% +You can adjust the volume of various parts of the sound system in your +computer by typing 'mixer <type> <volume>'. To get a list of what you can +adjust, just type 'mixer'. +% +You can automatically download and install binary packages by doing + + pkg install <package> + +This will also automatically install the packages that are dependencies +for the package you install (ie, the packages it needs in order to work.) +% +You can change the video mode on all consoles by adding something like +the following to /etc/rc.conf: + + allscreens="80x30" + +You can use "vidcontrol -i mode | grep T" for a list of supported text +modes. + -- Konstantinos Konstantinidis <kkonstan@duth.gr> +% +You can disable tcsh's terminal beep if you `set nobeep'. +% +You can install extra packages for FreeBSD by using the ports system. +If you have installed it, you can download, compile, and install software by +just typing + + # cd /usr/ports/<category>/<portname> + # make install && make clean + +as root. The ports infrastructure will download the software, change it so +it works on FreeBSD, compile it, install it, register the installation so it +will be possible to automatically uninstall it, and clean out the temporary +working space it used. You can remove an installed port you decide you do not +want after all by typing + + # cd /usr/ports/<category>/<portname> + # make deinstall + +as root. +% +You can look through a file in a nice text-based interface by typing + + less filename +% +You can make a log of your terminal session with script(1). +% +You can often get answers to your questions about FreeBSD by searching in the +FreeBSD mailing list archives at + + http://www.FreeBSD.org/search/search.html +% +You can open up a new split-screen window in (n)vi with :N or :E and then +use ^w to switch between the two. +% +You can permanently set environment variables for your shell by putting them +in a startup file for the shell. The name of the startup file varies +depending on the shell - csh and tcsh uses .login, bash, sh, ksh and zsh use +.profile. When using bash, sh, ksh or zsh, don't forget to export the +variable. +% +You can press Ctrl-D to quickly exit from a shell, or logout from a +login shell. + -- Konstantinos Konstantinidis <kkonstan@duth.gr> +% +You can press Ctrl-L while in the shell to clear the screen. +% +You can press up-arrow or down-arrow to walk through a list of +previous commands in tcsh. +% +You can search for documentation on a keyword by typing + + apropos keyword +% +You can `set autologout = 30' to have tcsh log you off automatically +if you leave the shell idle for more than 30 minutes. +% +You can use aliases to decrease the amount of typing you need to do to get +commands you commonly use. Examples of fairly popular aliases include (in +Bourne shell style, as in /bin/sh, bash, ksh, and zsh): + + alias lf="ls -FA" + alias ll="ls -lA" + alias su="su -m" + +In csh or tcsh, these would be + + alias lf ls -FA + alias ll ls -lA + alias su su -m + +To remove an alias, you can usually use 'unalias aliasname'. To list all +aliases, you can usually type just 'alias'. +% +You can use /etc/make.conf to control the options used to compile software +on this system. Example entries are in +/usr/share/examples/etc/make.conf. +% +You can use "pkg info" to see a list of packages you have installed. +% +You can use the 'fetch' command to retrieve files over ftp, http or https. + + fetch http://www.FreeBSD.org/index.html + +will download the front page of the FreeBSD web site. +% +You can use "whereis" to search standard binary, manual page and source +directories for the specified programs. This can be particularly handy +when you are trying to find where in the ports tree an application is. + +Try "whereis firefox" and "whereis whereis". + -- Konstantinos Konstantinidis <kkonstan@duth.gr> +% +Want to run the same command again? +In tcsh you can type "!!" +% +Want to go the directory you were just in? +Type "cd -" +% |
