Check These Out

copy paste multiple binary files
Useful when you have multiple files or binary files that you need to transfer to a different host and scp or the like is unavailable. To unpack on the destination host copy paste output using the opposite order: openssl enc -d -base64 | gunzip | tar -x Terminate openssl input using ^d Note: gzip is outside of tar because using -z in tar produces lots of extra padding.

Extract the emoticons regex from a running skype process
Skype has an internal regex which depicts the emoticons it supports. However you cannot simply search the binary file for it. This small 181 character line will do just that, provided skype is running. And of course, only works in linux.

Find the package that installed a command

find and grep Word docs
Find Word docs by filename in the current directory, convert each of them to plain text using antiword (taking care of spaces in filenames), then grep for a search term in the particular file. (Of course, it's better to save your data as plain text to make for easier grepping, but that's not always possible.) Requires antiword. Or you can modify it to use catdoc instead.
