  • Do you have an entire album in a unique file and want to split it in individual tracks? If you also have the cue file you can do it! Packages for Debian-based systems users: * cuetools shntool * FLAC (.flac): flac * WavPack (.wv): wavpack * Monkey's Audio (.ape): libmac2 monkeys-audio (deb http://www.debian-multimedia.org sid main) NOTE: "sid" packages are unstable, but I didn't have problems with them. If you prefer, use the "stable" version repository. To transfer the tags, you can use this (works with .flac, .ogg and .mp3): cuetag sample.cue split-track*.flac Show Sample Output


    5
    cuebreakpoints <cue file> | shnsplit -o <lossless audio type> <audio file>

  • The title is optional. Options: -t: expire time in milliseconds. -u: urgency (low, normal, critical). -i: icon path. On Debian-based systems you may need to install the 'libnotify-bin' package. Useful to advise when a wget download or a simulation ends. Example: wget URL ; notify-send "Done"


    47
    notify-send ["<title>"] "<body>"

  • Start screen in detached mode, i.e., already running on background. The command is optional, but what is the purpose on start a blank screen process that way? It's useful when invoking from a script (I manage to run many wget downloads in parallel, for example).


    16
    screen -d -m [<command>]

  • Sometimes Firefox crashes or is bad finished and the message the process is still running appear while it's not. This also works when you sharing account from a NIS server and try to open the browser on multiple computers.

  • This command is useful when you want to install the same packages on another fresh OS install for example. To do that, use: sudo dpkg --set-selections < LIST_FILE Show Sample Output


    11
    dpkg --get-selections > LIST_FILE

  • Packages: gmailfs fuse-utils libfuse2 gvfs-fuse Config files: /etc/gmailfs/gmailfs.conf; ~/.gmailfs.conf (make a copy from the another one) Unmount: fusermount -u /mount/path/ /etc/fstab (Optional): none /mount/path/ gmailfs noauto,user[,username=USERNAME,password=PASSWORD,fsname=VOLUME] 0 0 NOTES: - The options between [] are optional since they already setuped on the config files. - The '-p' flag shows a prompt for the password entry. - It's necessary to add the user to the 'fuse' group. You can do that with: sudo chgrp fuse /dev/fuse and sudo usermod -a -G fuse USER - The volume name is not needed but highly recommended to avoid file corruption. Also choose a non-trivial name. - Google doesn't approve the use of Gmail account other than e-mail purposes. So, I recommend the creation of a new account for this.


    5
    mount.gmailfs none /mount/path/ [-o username=USERNAME[,password=PASSWORD][,fsname=VOLUME]] [-p]

  • To install a theme use: sudo firefox -install-global-theme /path/to/theme You can get the .xpi or .jar file from the versions history on the add-on/theme page. NOTE: may not work in your system (Debian-based is an example).


    17
    sudo firefox -install-global-extension /path/to/add-on

  • Not so useful. Just a cool feature.


    7
    mplayer -vo aa <video file>

  • The download content part. NOTE: the '-c' seems to not work very well and the download stuck at 99% sometimes. Just finish wget with no problem. Also, the download may restart after complete. You can also cancel. I don't know if it is a wget or Rapidshare glitch since I don't have problems with Megaupload, for example. UPDATE: as pointed by roebek the restart glitch can be solved by the "-t 1" option. Thanks a lot.


    6
    wget -c -t 1 --load-cookies ~/.cookies/rapidshare <URL>
    o6291408 · 2009-03-28 09:13:35 5
  • In order to do that, first you need to save a cookie file with your account info. These commands do it (maybe you need to create the '.cookies' dir before). Also, you need to check the "Direct downloads" option on the Premium Zone >> Settings tab. You need to do this once (as long you maintain the file or your Rapidshare Premium account).


    4
    wget --save-cookies ~/.cookies/rapidshare --post-data "login=USERNAME&password=PASSWORD" -O - https://ssl.rapidshare.com/cgi-bin/premiumzone.cgi > /dev/null

happened to find this not bad software to keep my files and folders safe! Even the free trial version has the fantastic functions to protect any private files from being seen by anyone except me. With it I can encrypt, hide or lock anything I want, amazin
I noticed some spammer posted an advertisement here for "not bad" encryption. Unfortunately, their software only runs under Microsoft Windows and fails to work from the commandline. My shell script improves upon those two aspects, with no loss in security, using the exact same "military-grade" encryption technology, which has the ultra-cool codename "ROT-13". For extra security, I recommend running ROT-13 twice.

full path listing in /directory/path/* of javascript files.
file listing in /directory/path/* of specific files such as javascript(js) .

list files recursively by size

access to last touched or created file with arrow_up_key immediately after displaying the file list
Display recursive file list (newest file displayed at the end) and be free to access last file in the list simply by pressing arrow_up_key i.e. open it with joe editor. BTW IMHO the list of files with newest files at the end is often more informative. Put this 'lsa' function somewhere in your .bashrc and issue $ . ~/.bashrc or $ source ~/.bashrc to have access to the 'lsa' command immediately. . (the function appends command "joe last_file_in_the_list" at the end of command history)

Get AWS temporary credentials ready to export based on a MFA virtual appliance
You might want to secure your AWS operations requiring to use a MFA token. But then to use API or tools, you need to pass credentials generated with a MFA token. This commands asks you for the MFA code and retrieves these credentials using AWS Cli. To print the exports, you can use: `awk '{ print "export AWS_ACCESS_KEY_ID=\"" $1 "\"\n" "export AWS_SECRET_ACCESS_KEY=\"" $2 "\"\n" "export AWS_SESSION_TOKEN=\"" $3 "\"" }'` You must adapt the command line to include: * $MFA_IDis ARN of the virtual MFA or serial number of the physical one * TTL for the credentials

Recover a deleted file
grep searches through a file and prints out all the lines that match some pattern. Here, the pattern is some string that is known to be in the deleted file. The more specific this string can be, the better. The file being searched by grep (/dev/sda1) is the partition of the hard drive the deleted file used to reside in. The ?-a? flag tells grep to treat the hard drive partition, which is actually a binary file, as text. Since recovering the entire file would be nice instead of just the lines that are already known, context control is used. The flags ?-B 25 -A 100? tell grep to print out 25 lines before a match and 100 lines after a match. Be conservative with estimates on these numbers to ensure the entire file is included (when in doubt, guess bigger numbers). Excess data is easy to trim out of results, but if you find yourself with a truncated or incomplete file, you need to do this all over again. Finally, the ?> results.txt? instructs the computer to store the output of grep in a file called results.txt.

Find files changed between dates defined by ctime of two files specified by name
This command finds all the files whose status has changed between the ctime of the older and newer . Very useful if you can see from an ls listing a block of consecutive files you want to move or delete, but can't figure out exactly the time range by date.

Count threads of a jvm process
