  • tar and bz2 a set of folders as individual files

    I use screenflow to create and edit videos. The default storage for a single video is a folder. If I want to move that someplace, it's easier to zip up the folder and send it. If I'm making a series of short videos, I might have 10 folders. This will go through and make a single bz3 file for EACH folder.


    0
    for f in *screenflow ; do tar cvf "$f.tar.bz2" "$f"; done

  • wget, tar xzvf, cd, ls

    Combines a few repetitive tasks when compiling source code. Especially useful when a hypen in a file-name breaks tab completion. 1.) wget source.tar.gz 2.) tar xzvf source.tar.gz 3.) cd source 4.) ls From there you can run ./configure, make and etc. Show Sample Output


    -1
    wtzc () { wget "$@"; foo=`echo "$@" | sed 's:.*/::'`; tar xzvf $foo; blah=`echo $foo | sed 's:,*/::'`; bar=`echo $blah | sed -e 's/\(.*\)\..*/\1/' -e 's/\(.*\)\..*/\1/'`; cd $bar; ls; }

  • Extract 2 copies of .tar.gz content

    Sometimes you might need to have two copies of data that is in tar. You might unpack, and then copy, but if IO is slow, you might lower it by automatically writing it twice (or more times)

    mkdir copy{1,2}; gzip -dc file.tar.gz | tee >( tar x -C copy1/ ) | tar x -C copy2/

  • Copy files over network using compression

    This is useful for sending data between 2 computers that you have shell access to. Uses tar compression during transfer. Files are compressed & uncompressed automatically. Note the trailing dash on the listening side that makes netcat listen to stdin for data. on the listening side: sudo nc -lp 2022 | sudo tar -xvf - explanation: open netcat to -l listen on -p port 2022, take the data stream and pipe to tar -x extract, -v verbose, -f using file filename - means "stdin" on the sending side: tar -cvzf - ./*| nc -w 3 name_of_listening_host 2022 explanation: compress all files in current dir using tar -c create, -v verbose, -f using file, - filename - here means "stdout" because we're tar -c instead of tar -x, -w3 wait 3 seconds on stream termination and then end the connection to the listening host name_of_listening_host, on port 2022


    -2
    on the listening side: sudo nc -lp 2022 | sudo tar -xvf - and on the sending side: tar -cvzf - ./*| nc -w 3 name_of_listening_host 2022

  • create tar.gz archive

    Create a single tar.gz archive I know it's a very basic one, but it's one I keep forgetting. Show Sample Output

  • Bulk copy large blocks of data between File Systems (run as root iff you do not own all of the files!)

    Using tape archive create a tar file in Stdout (-) and pipe that into a compound command to extract the tar file from Stdin at the destination. This similar to "Copy via tar pipe ...", but copies across file systems boundaries. I prefer to use cp -pr for copying within the same file system. Show Sample Output


    -2
    tar cpof - src |( cd des; tar xpof -)

  • List files in tarballs

    This script will list all the files in the tarballs present on any folder or subfolder of the provided path. The while loop is for echoing the file name of the tarball before listing the files, so the tarball can be identified


    -2
    find <path> -name "*.tgz" -or -name "*.tar.gz" | while read file; do echo "$file: "; tar -tzf $file; done
    polaco · 2009-11-10 20:39:04 36
  • List files in tarballs

    The magic is performed by the parameter -t Show Sample Output


    -2
    for F in $(find ./ -name "*.tgz") ; do tar -tvzf $F ; done

  • transfer files locally to be sure that file permissions are kept correctly showing progress

    This may seem like a long command, but it is great for making sure all file permissions are kept in tact. What it is doing is streaming the files in a sub-shell and then untarring them in the target directory. Please note that the -z command should not be used for local files and no perfomance increase will be visible as overhead processing (CPU) will be evident, and will slow down the copy. You also may keep simple with, but you don't have the progress info: cp -rpf /some/directory /other/path Show Sample Output


    -2
    dir='path to file'; tar cpf - "$dir" | pv -s $(du -sb "$dir" | awk '{print $1}') | tar xpf - -C /other/path

  • Remove all files previously extracted from a tar(.gz) file.

    xargs deals badly with special characters (such as space, ' and "). To see the problem try this: touch important_file touch 'not important_file' ls not* | xargs rm Parallel https://savannah.nongnu.org/projects/parallel/ does not have this problem.


    -2
    tar -tf <file.tar.gz> | parallel rm

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.

Query Wikipedia via console over DNS
Query Wikipedia by issuing a DNS query for a TXT record. The TXT record will also include a short URL to the complete corresponding Wikipedia entry.You can also write a little shell script like: $ $ cat wikisole.sh $ #!/bin/sh $ dig +short txt ${1}.wp.dg.cx and run it like $ ./wikisole.sh unix were your first option ($1) will be used as search term.

grab all commandlinefu shell functions into a single file, suitable for sourcing.
Each shell function has its own summary line, as a comment. If there are multiple shell functions with the same name, the function with the highest number of votes is put into the file. Note: added 'grep -v' to the end of the pipeline, to eliminate extraneous lines containing only '--'. Thanks to matthewbauer for pointing this out.

Update your OpenDNS network ip
Intended for dynamic ip OpenDNS users, this command will update your OpenDNS network IP. For getting your IP, you can use one of the many one-liners here on commandlinefu. Example: I use this in a script which is run by kppp after it has successfully connected to my ISP: --- #!/bin/bash IP="`curl -s http://checkip.dyndns.org/ | grep -o '[[:digit:].]\+'`" PW="hex-obfuscated-pw-here" if [ "$IP" == "" ] ; then echo 'Not online.' ; exit 1 else wget -q --user=topsecret --password="`echo $PW | xxd -ps -r`" 'https://updates.opendns.com/nic/update?hostname=myhostname&myip='"$IP" -O - /etc/init.d/ntp-client restart & fi --- PS: DynDNS should use a similar method, if you know the URL, please post a comment. (Something with members.dyndns.org, if I recall correctly)

Multiple variable assignments from command output in BASH
This version uses read instead of eval.

show framebuffer console modes to use in grub vga option
look at /boot/grub/menu.lst for somethig like: ## additional options to use with the default boot option, but not with the ## alternatives ## e.g. defoptions=vga=791 resume=/dev/hda5 ## defoptions=vga=795 # defoptions=vga=873 ## altoption boot targets option ## multiple altoptions lines are allowed ## e.g. altoptions=(extra menu suffix) extra boot options ## altoptions=(recovery) single # altoptions=(verbose mode) vga=775 debug # altoptions=(console mode) vga=ask # altoptions=(graphic mode) quiet splash # altoptions=(recovery mode) single vga=(decimal value) is framebuffer mode

find unreadable file

Log the current memory statistics frequently to syslog
Uses logger in a while loop to log memory statistics frequently into the local syslog server.

Check how far along (in %) your program is in a file
Imagine you've started a long-running process that involves piping data, but you forgot to add the progress-bar option to a command. e.g. $ xz -dc bigdata.xz | complicated-processing-program > summary . This command uses lsof to see how much data xz has read from the file. $ lsof -o0 -o -Fo FILENAME Display offsets (-o), in decimal (-o0), in parseable form (-Fo) This will output something like: . p12607 f3 o0t45187072 . Process id (p), File Descriptor (f), Offset (o) . We stat the file to get its size $ stat -c %s FILENAME . Then we plug the values into awk. Split the line at the letter t: -Ft Define a variable for the file's size: -s=$(stat...) Only work on the offset line: /^o/ . Note this command was tested using the Linux version of lsof. Because it uses lsof's batch option (-F) it may be portable. . Thanks to @unhammer for the brilliant idea.

A DESTRUCTIVE command to render a drive unbootable
THIS COMMAND IS DESTRUCTIVE. That said, lets assume you want to render your boot drive unbootable and reboot your machine. Maybe you want it to boot off the network and kickstart from a boot server for a fresh OS install. Replace /dev/fd0 with the device name of your boot drive and this DESTRUCTIVE command will render your drive unbootable. Your BIOS boot priority should be set to boot from HD first, then LAN.
