Commands using wget (286)

  • Get gzip compressed web page using wget.

    Like the original command, but the -f allows this one to succeed even if the website returns uncompressed data. From gzip(1) on the -f flag: If the input data is not in a format recognized by gzip, and if the --stdout is also given, copy the input data without change to the standard output: let zcat behave as cat.

  • print latest (top 10, top 3 or *) commandlinefu.com commands

    This lengthy cryptic line will print the latest top 10 commandlinefu.com posts without their summaries. To print also their respective summaries use the following (even bigger) command line: wget -qO - http://www.commandlinefu.com/feed/tenup | xmlstarlet sel -T -t -o '<doc>' -n -t -m rss/channel/item -o '<item>' -n -o '<title>' -v title -o '</title>' -n -o '<description>' -v description -o '</description>' -n -o '</item>' -n -t -o '</doc>' | xmlstarlet sel -T -t -m doc/item -v description/code -n -v title -n -n It is recommended to include this line into a shell script to be easily run, as I do myself. You could also use the following URLs to browse the top 3 commands: wget -qO - http://www.commandlinefu.com/feed/threeup | xmlstarlet ... .. or all others: wget -qO - http://feeds2.feedburner.com/Command-line-fu | xmlstarlet ... PS: You need to install "xmlstarlet" to run it. It is found in Debian APT repositories (apt-get install xmlstarlet) or under the http://xmlstar.sourceforge.net/ URL. Show Sample Output

  • Run remote web page, but don't save the results

    I don't know if the --spider option works to execute a script, but it might be worth trying. Note that the Drupal project uses the following in a cron job. wget -O - -q http://localhost/drupal/cron.php The output is sent to standard out so it can be logged by cron.

  • Define words with google. (busybox version)

    This is a minimalistic version of the ubiquitious Google definition screen scraper. This version was designed not only to run fast, but to work using BusyBox. BusyBox is a collection of basic Unix tools that have been compiled into a single binary to save space on tiny installations of Unix. For example, although my phone doesn't have perl or the GNU utilities, it does have BusyBox's stripped down versions of wget, tr, and sed. It turns out that those tools suffice for many tasks. Known Bugs: This script does not handle HTML entities at all. I don't think there's an easy way to do that within BusyBox, but I'd love to see it if someone could do it. Also, this script can only define a single word, not phrases. (Well, you could if you typed in %20, but that'd be gross.) Lastly, this script does not show the URL where definitions were found. Given the randomness of the Net, that last bit of information is often key. Show Sample Output

    wget -q -U busybox -O- "http://www.google.com/search?ie=UTF8&q=define%3A$1" | tr '<' '\n' | sed -n 's/^li>\(.*\)/\1\n/p'

  • download and run script from trusted webserver

    This is a simple command that you can run complex shell scripts via ssh. For instance if you would have to run the same process on several hundred hosts. There is no security so you have to trust the server that is sourcing this script.

  • View the newest xkcd comic.

    This function displays the latest comic from xkcd.com. One of the best things about xkcd is the title text when you hover over the comic, so this function also displays that after you close the comic. To get a random xkcd comic use the following: xkcdrandom() { wget -qO- http://dynamic.xkcd.com/comic/random | sed -n 's#^<img src="\(http://imgs.[^"]\+\)"\s\+title="\(.\+\?\)"\salt.\+$#eog "\1"\necho '"'\2'#p" | bash; } These are just a bit shorter than the ones eigthmillion wrote, however his version didn't work as expected on my laptop for some reason (I got the title-tag first), so these build a command which is executed by bash.

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.

Don't like the cut command? Tired of typing awk '{print $xxx}', try this

Count the number of deleted files
It does not work without the verbose mode (-v is important)

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" }

Find out current working directory of a process

See how many more processes are allowed, awesome!
There is a limit to how many processes you can run at the same time for each user, especially with web hosts. If the maximum # of processes for your user is 200, then the following sets OPTIMUM_P to 100. $ OPTIMUM_P=$(( (`ulimit -u` - `find /proc -maxdepth 1 \( -user $USER -o -group $GROUPNAME \) -type d|wc -l`) / 2 )) This is very useful in scripts because this is such a fast low-resource-intensive (compared to ps, who, lsof, etc) way to determine how many processes are currently running for whichever user. The number of currently running processes is subtracted from the high limit setup for the account (see limits.conf, pam, initscript). An easy to understand example- this searches the current directory for shell scripts, and runs up to 100 'file' commands at the same time, greatly speeding up the command. $ find . -type f | xargs -P $OPTIMUM_P -iFNAME file FNAME | sed -n '/shell script text/p' I am using it in my http://www.askapache.com/linux-unix/bash_profile-functions-advanced-shell.html especially for the xargs command. Xargs has a -P option that lets you specify how many processes to run at the same time. For instance if you have 1000 urls in a text file and wanted to download all of them fast with curl, you could download 100 at a time (check ps output on a separate [pt]ty for proof) like this: $ cat url-list.txt | xargs -I '{}' -P $OPTIMUM_P curl -O '{}' I like to do things as fast as possible on my servers. I have several types of servers and hosting environments, some with very restrictive jail shells with 20processes limit, some with 200, some with 8000, so for the jailed shells my xargs -P10 would kill my shell or dump core. Using the above I can set the -P value dynamically, so xargs always works, like this. $ cat url-list.txt | xargs -I '{}' -P $OPTIMUM_P curl -O '{}' If you were building a process-killer (very common for cheap hosting) this would also be handy. Note that if you are only allowed 20 or so processes, you should just use -P1 with xargs.

split a string (3)

A signal trap that logs when your script was killed and what other processes were running at that time
trap is the bash builtin that allows you to execute commands when the current script receives a particular signal. Uses $0 for the script name, $$ for the script PID, tee to output to STDOUT as well as a log file and ps to log other running processes.

take a look to command before action
add |sh when you agree the list, I often use that method to prevent typos in dangerous or long operations

Sum columns from CSV column $COL

Launch a game, like Tetris, when apt-get installing an app larger than 50 Megabytes
Change the APP variable's value to whatever you want to install. Depending on how fast your machine is, you'll want to adjust the value 50 to something else. You might also want to play a different game than Gnometris - just make sure it's a GUI game.
