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

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;

What's this?

commandlinefu.com is the place to record those command-line gems that you return to again and again. That way others can gain from your CLI wisdom and you from theirs too. All commands can be commented on, discussed and voted up or down.

Rename files in batch

bash: display disks by id, UUID and HW path

Shows a tree of the disks. Requires "tree"

Extract the MBR ID of a device

Useful when you want to know the mbrid of a device - for the purpose of making it bootable. Certain hybridiso distros, for eg the OpenSUSE live ISO uses the mbrid to find the live media. Use this command to find out the mbrid of your USB drive and then edit the /grub/mbrid file to match it.

List latest 5 modified files recursively

The output format is given by the -printf parameter: %T@ = modify time in seconds since Jan. 1, 1970, 00:00 GMT, with fractional part. Mandatory, hidden in the end. %TY-%Tm-%Td %TH:%TM:%.2TS = modify time as YYYY-MM-DD HH:MM:SS. Optional. %p = file path Refer to http://linux.die.net/man/1/find for more about -printf formatting. ------------------------ sort -nr = sort numerically and reverse (higher values - most recent timestamp - first) head -n 5 = get only 5 first lines (change 5 to whatever you want) cut -f2- -d" " = trim first field (timestamp, used only for sorting) ------------------------ Very useful for building scripts for detecting malicious files upload and malware injections.

Show network throughput

Real gurus don't need fancy tools like iftop or jnettop.

Install pip with Proxy

Installs pip packages defining a proxy

Find all the links to a file

This command finds and prints all the symbolic and hard links to a file. Note that the file argument itself be a link and it will find the original file as well. You can also do this with the inode number for a file or directory by first using stat or ls or some other tool to get the number like so: $ stat -Lc %i file or $ ls -Hid file And then using: $ find -L / -inum INODE_NUMBER -exec ls -ld {} +

Convert seconds to [DD:][HH:]MM:SS

Converts any number of seconds into days, hours, minutes and seconds. sec2dhms() { declare -i SS="$1" D=$(( SS / 86400 )) H=$(( SS % 86400 / 3600 )) M=$(( SS % 3600 / 60 )) S=$(( SS % 60 )) [ "$D" -gt 0 ] && echo -n "${D}:" [ "$H" -gt 0 ] && printf "%02g:" "$H" printf "%02g:%02g\n" "$M" "$S" }

Use acpi and notify-send to report current temperature every five minutes.

Use acpi and notify-send to report current temperature every five minutes. Works best in a shell script run at startup. acpi is called for temperature and fed to notify-send for a tooltip. After waiting five minutes, it will start over.

Find files that are older than x days

Find files that are older than x days in the working directory and list them. This will recurse all the sub-directories inside the working directory. By changing the value for -mtime, you can adjust the time and by replacing the ls command with, say, rm, you can remove those files if you wish to.
