  • Find corrupted jpeg image files

    Finds all corrupted jpeg files in current directory and its subdirectories. Displays the error or warning found. The jpeginfo is part of the jpeginfo package in debian. Should you wish to only get corrupted filenames, use cut to extract them : find ./ -name *jpg -exec jpeginfo -c {} \; | grep -E "WARNING|ERROR" | cut -d " " -f 1 Show Sample Output

  • sync a directory of corrupted jpeg with a source directory

    Find all corrupted jpeg in the current directory, find a file with the same name in a source directory hierarchy and copy it over the corrupted jpeg file. Convenient to run on a large bunch of jpeg files copied from an unsure medium. Needs the jpeginfo tool, found in the jpeginfo package (on debian at least).

  • Find corrupted jpeg image files

    This checks jpeg data and metadata, should be grepped as needed, maybe a -B1 Warning for the first, and a -E "WARNING|ERROR" for the second part....

Find usb device in realtime
Using this command you can track a moment when usb device was attached.

Smart `cd`.. cd to the file directory if you try to cd to a file
This little function will smarten 'cd'. If you try to cd into a file (which I guess we all have done), it cd's into the directory of that file instead. I had to use nesten if's, to get cd to still work with 'cd' (to get to $HOME), 'cd -' (to get to last directory), and 'cd foo\ bar'.

Schedule a script or command in x num hours, silently run in the background even if logged out
This is helpful for shell scripts, I use it in my custom php install script to schedule to delete the build files in 3 hours, as the php install script is completely automated and is made to run slow. Does require at, which some environments without crontab still do have. You can add as many commands to the at you want. Here's how I delete them in case the script gets killed. (trapped) atq |awk '{print $1}'|xargs -iJ atrm J &>/dev/null

Symlink all files from a base directory to a target directory

Email someone if a web page has been updated.
A cronjob command line to email someone when a webpages homepage is updated.

find geographical location of an ip address
I save this to bin/iptrace and run "iptrace ipaddress" to get the Country, City and State of an ip address using the http://ipadress.com service. I add the following to my script to get a tinyurl of the map as well: URL=`lynx -dump http://www.ip-adress.com/ip_tracer/?QRY=$1|grep details|awk '{print $2}'` lynx -dump http://tinyurl.com/create.php?url=$URL|grep tinyurl|grep "19. http"|awk '{print $2}'

Set CDPATH to ease navigation
CDPATH tells the cd command to look in this colon-separated list of directories for your destination. My preferred order are 1) the current directory, specified by the empty string between the = and the first colon, 2) the parent directory (so that I can cd lib instead of cd ../lib), 3) my home directory, and 4) my ~/projects directory.

renames multiple files that match the pattern
Useful when you want to quickly rename a bunch of files.

Copy ssh keys to user@host to enable password-less ssh logins.
To generate the keys use the command ssh-keygen
