This is a beginning script. You can create a file with > filename. You can also use diff to compare output run at different times to verify no change in your files. I apologize in advance if this is too simple. For some it should be a start.
Create a exact mirror of the local folder "/root/files", on remote server 'remote_server' using SSH command (listening on port 22)
(all files & folders on destination server/folder will be deleted)
Add the QR code image on your webpage, business card ., etc, so people can scan it and quick add to their Contact Address Book. Tested on iPhone with QRreader.
for when a program is hogging the sound output. finds, and kills. add -9 to the end for wedged processes. add in 'grep ^program' after lsof to filter.
Install the Linux kernel headers for currently running kernel version on Debian-based systems via apt-get
The Linux /dev/full file simulates a "disk full" condition, and can be used to verify how a program handles this situation.
In particular, several programming language implementations do not print error diagnostics (nor exit with error status) when I/O errors like this occur, unless the programmer has taken additional steps. That is, simple code in these languages does not fail safely. In addition to Perl, C, C++, Tcl, and Lua (for some functions) also appear not to fail safely.
Alternative for machines without ssh-copy-id
$ wget -qO - "http://www.google.com/dictionary/json?callback=dict_api.callbacks.id100&q=steering+wheel&sl=en&tl=en&restrict=pr,de&client=te"
this does the actual google dictionary query, returns a JSON string encapsulated in some fancy tag
$ sed 's/dict_api\.callbacks.id100.//'
here we remove the tag beginning
$ sed 's/,200,null)//'
and here the tag end
There are also some special characters which could cause problems with some JSON parsers, so if you get some errors, this is probably the case (sed is your friend).
I laso like to trim the "webDefinitions" part, because it (sometimes) contains misleading information.
$ sed 's/\,\"webDefinitions.*//'
(but remember to append a "}" at the end, because the JSON string will be invalid)
The output also contains links to mp3 files with pronounciation.
As of now, this is only usable in the English language. If you choose other than English, you will only get webDefinitions (which are crap).
