Search commandlinefu.com from the command line using the API

Search for one/many words on commandlinefu, results in vim for easy copy, manipulation. The -R flag is for readonly mode...you can still write to a file, but vim won't prompt for save on quit. What I'd really like is a way to do this from within vim in a new tab. Something like :Tex path/to/file but :cmdfu search terms

Search commandlinefu.com and display with VIMs syntax highlighting!

Multi-argument version, but with VIM loveliness :D

Search big files with long lines

This is a handy way to circumvent the "Maximum line length of 2048 exceeded" grep error. Once you have run the above command (or put it in your .bashrc), files can be searched using: lgrep search-string /file/to/search
This is sample output - yours may be different.

lgrep() { string=$1; file=$2; awk -v String=${string} '$0 ~ String' ${file}; }

Search and replace in multiple files and save them with the same names - quickly and effectively!

Yeah, there are many ways to do that. Doing with sed by using a for loop is my favourite, because these are two basic things in all *nix environments. Sed by default does not allow to save the output in the same files so we'll use mv to do that in batch along with the sed. Show Sample Output

```
No standard output on screen... just hit and boom. So, by the rule of the thumb first create a backup and then execute  or try to execute on some dummy files first.
```

for files in $(ls -A directory_name); do sed 's/search/replaced/g' $files > $files.new && mv $files.new $files; done;

ls only directories

Like normal ls, but only lists directories. Can be used with -l to get more details (ls -lad */)

In-Place search/replace with datestamped backup

Does an in situ search-replace but leaves a datestamped backup. A variation with more precision: sed -i.`date +%Y%m%d%H%M%S 's/pattern/replace' [filename]

Find out my Linux distribution name and version

Override and update your locally modified files through cvs..

Determine space taken by files of certain type

Just how much space are those zillions of database logs taking up ? How much will you gain on a compression rate of say 80% ? This little line gives you a good start for your calculations.

Show a listing of open mailbox files (or whatever you want to modify it to show)

Which processes are listening on a specific port (e.g. port 80)

swap out "80" for your port of interest. Can use port number or named ports e.g. "http"

Create named LUKS encrypted volume

You need to be root to do this. So check the command before running it. You enter the same password for Enter LUKS passphrase: Verify passphrase: Enter passphrase for /dev/loopn: ___ You can then copy the .img file to somewhere else. Loop it it with losetup -f IMAGENAME.img and then mount it with a file manager (eg nemo) or run mount /dev/loopn /media/mountfolder Acts similar to a mounted flash drive

Which processes are listening on a specific port (e.g. port 80)

swap out "80" for your port of interest. Can use port number or named ports e.g. "http"

Destroy all disks on system simultaneously

This command will use the fdisk utility to find all block devices on your system, and overwrite them with data from the /dev/urandom non-blocking random number generator. CAUTION: This will irrevocably erase EVERY SINGLE physical block storage device visible to the fdisk utility, including plugged USB devices, RAID sets, LVM, etc.
