  • Add permanent line numbers to a file without creating a temp file. The rm command deletes file10 while the nl command works on the open file descriptor of file10 which it outputs into a new file again named file10. The new file10 will now be numbered in the same directory with the same file name and content as before, but it will in fact be a new file, using (ls -i) to show its inode number will prove this.


    3
    { rm -f file10 && nl > file10; } < file10

  • Copy this function to command line, press 'Enter' 'f'' 'Enter' to execute (sentence on the left written only for newbies). Hint 'e|x|v|1..9' in front of displayed last modified file name means: "Press 'e' for edit,'x' for execute,'v' for view or a digit-key '1..9' to touch one file from the recent files list to be last modified" and suggested (hidden files are listed too, else remove 'a' from 'ls -tarp' statement if not intended). If you find this function useful you can then rename it if needed and append or include into your ~/.bashrc config script. With the command . ~/.bashrc the function then can be made immediately available. In the body of the function modifications can be made, i.e. replaced joe editor command or added new option into case statement, for example 'o) exo-open $h;;' command for opening file with default application - or something else (here could not be added since the function would exceed 255 chars). To cancel execution of function started is no need to press Ctrl-C - if the mind changed and want to leave simple Enter-press is enough. Once defined, this function can with typeset -f f command be displayed in easy readable form Show Sample Output

  • Print a git log (in reverse order) giving a reference relative to HEAD. HEAD (the current revision) can also be referred to as HEAD~0 The previous revision is HEAD~1 then HEAD~2 etc. . Add line numbers to the git output, starting at zero: ... | nl -v0 | ... . Insert the string 'HEAD~' before the number using sed: ... | sed 's/^ \+/&HEAD~/' . Thanks to bartonski for the idea :-) Show Sample Output

  • This function is used to sort selected lines of a text file to the end of that file. Especially useful in cases where human intervention is necessary to sort out parts of a file. Let's say that you have a text file which contains the words rough slimy red fluff dough For whatever reason, you want to sort all words rhyming with 'tough' to the bottom of the file, and all words denoting colors to the top, while keeping the order of the rest of the file intact. '$EDITOR' will open, showing all of the lines in the given file, numbered with '0' padding. Adding a '~' to the beginning of the line will cause the line to sort to the end of the file, adding '!' will cause it to sort to the beginning. Show Sample Output

  • usage: dng BRE [selection] default selection is the last match DNS is ok, but although domainnames may be easier to remember than IP numbers, it still requires typing them out. This can be error-prone. Even more so than typing IPv4 numbers, depending on the domainname, its length and complexity.

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" }

Find all videos under current directory
Uses mime-type of files rather than relying on file extensions to find files of a certain type. This can obviously be extended to finding files of any other type as well.. like plain text files, audio, etc.. In reference to displaying the total hours of video (which was earlier posted in command line fu, but relied on the user having to supply all possible video file formats) we can now do better: $ find ./ -type f -print0 | xargs -0 file -iNf - | grep video | cut -d: -f1 | xargs -d'\n' /usr/share/doc/mplayer/examples/midentify | grep ID_LENGTH | awk -F "=" '{sum += $2} END {print sum/60/60; print "hours"}'

Get AWS temporary credentials ready to export based on a MFA virtual appliance
You might want to secure your AWS operations requiring to use a MFA token. But then to use API or tools, you need to pass credentials generated with a MFA token. This commands asks you for the MFA code and retrieves these credentials using AWS Cli. To print the exports, you can use: `awk '{ print "export AWS_ACCESS_KEY_ID=\"" $1 "\"\n" "export AWS_SECRET_ACCESS_KEY=\"" $2 "\"\n" "export AWS_SESSION_TOKEN=\"" $3 "\"" }'` You must adapt the command line to include: * $MFA_IDis ARN of the virtual MFA or serial number of the physical one * TTL for the credentials

Get My Public IP Address

Play Mediafile in multipart RAR archive on the fly with buffer to seek back and forth
Fire this up in the directory of the RAR achived files to watch any archived movie tv-show or other media without having to unpack it. I also added a cache/buffer to be able to seek back and forth.

Reboot as a different OS in Grub
This will reboot as the Grub 2 option.

search for files or directories, then show a sorted list of just the unique directories where the matches occur
Ever use 'locate' to find a common phrase in a filename or directory name? Often you'll get a huge list of matches, many of which are redundant, and typically the results are not sorted. This command will 'locate' your search phrase, then show you a sorted list of just the relevant directories, with no duplications. So, for example, maybe you have installed several versions of the java jre and you want to track down every directory where files matching "java" might exist. Well, a 'locate java' is likely to return a huge list with many repeated directories since many files in one directory could contain the phrase "java". This command will whittle down the results to a minimal list of unique directory names where your search phrase finds a match.
