  • change gpeXX by the culprit you discovered on phase 1 In case of this example, the culprit is the biggest number, ie, gpe1C /sys/firmware/acpi/interrupts/ff_gbl_lock: 0 enabled /sys/firmware/acpi/interrupts/gpe01: 0 enabled /sys/firmware/acpi/interrupts/gpe06: 0 enabled /sys/firmware/acpi/interrupts/gpe17: 2 enabled /sys/firmware/acpi/interrupts/gpe18: 0 enabled /sys/firmware/acpi/interrupts/gpe1C: 19 enabled This procedure,if solved this universal issue all linix distros are experimenting for more than 2 years, may be included at startup, via cron. But try first commandline.

  • I have a custmer's Geovision DVR installed on a closed proxi (only logme-in reaches it). I have to check for reliability but logmein hangs and is too slow a process I made the Geovision software send e-mail every minute to the www.spam.la site. All this script does is to retrieve the e-mail header from spam.la ( no login!), filtering sender, stopping at the first occurrence of the word "secs" ( the age of the last e-mail ). The result is the age of the sender's last e-mail, tiny published on top of my screen once a minute. I can refresh www.spam.la via web browser, but have other things to do. I use it inside Kalarm ( kde task schedule ) set to 1 minute repeat. It can be done without kalarm, using Watch outside the script. Try it out now using my account = geo1 ( change sender by geo1 in this script) Needs curl , osd-bin

  • Strip my code to: wmctrl -o 0,0 # autorotates to the first face. In fact [0-1279],0 wmctrl - 1280,0 # goes to the second face wmctrl -o 2560,0 # goes to the third face, and so on. # Use multiples of the horizontal display resolution. My example work for 1280x800 display, been 1280 the number of interest. Tweak the number, try a biiiig one and see your cube spinning... I put a complex example to show how fun things can be, even for my ademco and paradox alarm central network advisor interface xpto etc. It rotates two faces, print the alarm message, and goes back tho where it was. Tested on BIGLINUX 4.2, equivalent to ubuntu LTS hardy. Do not forget to activate 3D efects ( compiz cube ) Show Sample Output

  • My firefox overheats my cpu, sometimes above 90 degrees Celsius ( hence the name? ) To keep an eye on temperature, I put this command inside KAlarm ( a kind of cron) to be repeated every minute, for 5 seconds, color red ( default for osd_cat). Its pretty, ultra small, displays a micro 2 lines text on every desktop and over everything and do not steal focus or interrupt any task. I get the information passively, in the low profile bottom of the screen. Of course you can use it inside a terminal. Just do it: watch -n 60 'acpi -t | osd_cat -p bottom'

    acpi -t | osd_cat -p bottom

  • Usefull as a light blink to remember events, mails, intrusions, etc... yet another output Since nobody ever uses the scroll lock function... Usefull to interface a linux system with some hardware, for example, opto interfacing the keyboard led to a relay to remotely reset, etc. ( a simple LDR glued over the LED will do the trick ) xset led 3 turns on the third led, ie, Scroll lock xset -led 3 turns it off xset led 1 turns on Numerical Lock led ( doesn t work on all computer ) xset led 2 turns on Caps Lock led ( idem ) Using it as a reset watchdog, the relay expected light pulses. Shall the computer hangs, the relay releases and reset the machine ( discharge of a capacitor ) ;-)

  • Fully recharge your computer battery and start this script. It will create or clean the file named battery.txt, print a start on it and every minute it will append a time stamp to it. Batteries last few hours, and each hour will have 60 lines of time stamping. Really good for assuring the system was tested in real life with no surprises. The last time stamp inside the battery.txt file is of interest. It is the time the computer went off, as the battery was dead! Turn on your computer after that, on AC power of course, and open battery.txt. Read the first and last time stamps and now you really know if you can trust your computer sensors. If you want a simple line of text inside the battery.txt file, use this: watch -n 60 'date > battery.txt' The time of death will be printed inside Show Sample Output

  • Speaks whatever comes in via stdin (-v pt = portuguese, default = englisg) ..speech part of keyboard event talker. Made to accomplish a simple alarm central based on a cheap keyboard circuit.

What's this?

commandlinefu.com is the place to record those command-line gems that you return to again and again. That way others can gain from your CLI wisdom and you from theirs too. All commands can be commented on, discussed and voted up or down.

Share Your Commands


Check These Out

Quickly create an alias for changing into the current directory
Put the function in your .bashrc and use "map [alias]" to create the alias you want. Just be careful to not override an existing alias.

print file without duplicated lines usind awk
show file withou duplicated lines

list block devices
Shows all block devices in a tree with descruptions of what they are.

Find the package that installed a command

Run a command multiple times with different subcommands
it's nice to be able to use the command `ls program.{h,c,cpp}`. This expands to `ls program.h program.c program.cpp`. Note: This is a text expansion, not a shell wildcard type expansion that looks at matching file names to calculate the expansion. More details at http://www.linuxjournal.com/content/bash-brace-expansion I often run multiple commands (like apt-get) one after the other with different subcommands. Just for fun this wraps the whole thing into a single line that uses brace expansion.

Generate a random password 30 characters long

Find files that are older than x days
Find files that are older than x days in the working directory and list them. This will recurse all the sub-directories inside the working directory. By changing the value for -mtime, you can adjust the time and by replacing the ls command with, say, rm, you can remove those files if you wish to.

Convert seconds to [DD:][HH:]MM:SS
Converts any number of seconds into days, hours, minutes and seconds. sec2dhms() { declare -i SS="$1" D=$(( SS / 86400 )) H=$(( SS % 86400 / 3600 )) M=$(( SS % 3600 / 60 )) S=$(( SS % 60 )) [ "$D" -gt 0 ] && echo -n "${D}:" [ "$H" -gt 0 ] && printf "%02g:" "$H" printf "%02g:%02g\n" "$M" "$S" }

sort the contents of a text file in place.
sorts the contents of a file without the need for a second file to take the sorted output. This was previously entered as `sort -g list.txt -o $_` but as others have pointed out the $_ references the previous command. so this would've worked had that been the second part of a command joined with && like: cat list.txt && sort -g list.txt -o $_ The user below me Robin had the most correct command.

Position the cursor under the current directory line
In case you're like me and like your commands to start on clean lines, especially when you're deep into a 10-level directory tree. This can be added to .bashrc.
