  • find the biggest files recursively, no matter how many

    This command will find the biggest files recursively under a certain directory, no matter if they are too many. If you try the regular commands ("find -type f -exec ls -laSr {} +" or "find -type f -print0 | xargs -0 ls -laSr") the sorting won't be correct because of command line arguments limit. This command won't use command line arguments to sort the files and will display the sorted list correctly. Show Sample Output


    10
    find . -type f -printf '%20s %p\n' | sort -n | cut -b22- | tr '\n' '\000' | xargs -0 ls -laSr

  • Advanced LS Output using Find for Formatted/Sortable File Stat info

    I love this function because it tells me everything I want to know about files, more than stat, more than ls. It's very useful and infinitely expandable. find $PWD -maxdepth 1 -printf '%.5m %10M %#9u:%-9g %#5U:%-5G [%AD | %TD | %CD] [%Y] %p\n' | sort -rgbS 50% 00761 drwxrw---x askapache:askapache 777:666 [06/10/10 | 06/10/10 | 06/10/10] [d] /web/cg/tmp The key is: # -printf '%.5m %10M %#9u:%-9g %#5U:%-5G [%AD | %TD | %CD] [%Y] %p\n' which believe it or not took me hundreds of tweaking before I was happy with the output. You can easily use this within a function to do whatever you want.. This simple function works recursively if you call it with -r as an argument, and sorts by file permissions. lsl(){ O="-maxdepth 1";sed -n '/-r/!Q1'<<<$@ &&O=;find $PWD $O -printf '%.5m %10M %#9u:%-9g %#5U:%-5G [%AD | %TD | %CD] [%Y] %p\n'|sort -rgbS 50%; } Personally I'm using this function because: lll () { local a KS="1 -r -g"; sed -n '/-sort=/!Q1' <<< $@ && KS=`sed 's/.*-sort=\(.*\)/\1/g'<<<$@`; find $PWD -maxdepth 1 -printf '%.5m %10M %#9u:%-9g %#5U:%-5G [%AD | %TD | %CD] [%Y] %p\n'|sort -k$KS -bS 50%; } # i can sort by user lll -sort=3 # or sort by group reversed lll -sort=4 -r # and sort by modification time lll -sort=6 If anyone wants to help me make this function handle multiple dirs/files like ls, go for it and I would appreciate it.. Something very minimal would be awesome.. maybe like: for a; do lll $a; done Note this uses the latest version of GNU find built from source, easy to build from gnu ftp tarball.

  • find the 10 latest (modified) files

  • Quick case-insenstive partial filename search

    This is a simple command, but extremely useful. It's a quick way to search the file names in the current directory for a substring. Normally people use "ls *term*" but that requires the stars and is not case insensitive. Color (for both ls and grep) is an added bonus.


    6
    alias lg='ls --color=always | grep --color=always -i'

  • Sort files in multiple directories by date

    This sorts files in multiple directories by their modification date. Note that sorting is done at the end using "sort", instead of using the "-ltr" options to "ls". This ensures correct results when sorting a large number of files, in which case "find" will call "ls" multiple times.


    4
    find . -type f -exec ls -l --full-time {} + | sort -k 6,7

  • List directories recursively showing its sizes using only ls and grep

    ls -lhR Lists everithing using -l "long listing format" wich includes the space used by the folder. Displays it in -h "human readable form" (i.e. 2.2G, 32K), and -R recurses subfolders. grep -e using a regex, show lines containing the word "total" or a ":" at the end of the line (those with the name of the folder) only. Show Sample Output


    4
    ls -lhR | grep -e "total\|:$"

  • STAT Function showing ALL info, stat options, and descriptions

    This shows every bit of information that stat can get for any file, dir, fifo, etc. It's great because it also shows the format and explains it for each format option. If you just want stat help, create this handy alias 'stath' to display all format options with explanations. alias stath="stat --h|sed '/Th/,/NO/!d;/%/!d'" To display on 2 lines: ( F=/etc/screenrc N=c IFS=$'\n'; for L in $(sed 's/%Z./%Z\n/'<<<`stat --h|sed -n '/^ *%/s/^ *%\(.\).*$/\1:%\1/p'`); do G=$(echo "stat -$N '$L' \"$F\""); eval $G; N=fc;done; ) For a similarly powerful stat-like function optimized for pretty output (and can sort by any field), check out the "lll" function http://www.commandlinefu.com/commands/view/5815/advanced-ls-output-using-find-for-formattedsortable-file-stat-info From my .bash_profile -> http://www.askapache.com/linux-unix/bash_profile-functions-advanced-shell.html Show Sample Output

  • Show most common words in filenames

    I'm sure there's a more elegant sed version for the tr + grep section.

  • Graphical tree of sub-directories with files

    The command finds every item within the directory and edits the output so that subdirectories are and files are output much like the tree command Show Sample Output

  • Mac OS X: Change Color of the ls Command

    I use terminal with black background on the Mac. Unfortunately, the default ls color for the directory is blue, which is very hard to see. By including the line above in my ~/.bash_profile file, I changed the directory's color to cyan, which is easer to see. For more information on the syntax of the LSCOLORS shell variable: man ls I tested this command on Mac OS X Leopard

  • List contents of tar archive within a compressed 7zip archive

    Sometimes it is handy to be able to list contents of a tar file within a compressed archive, such as 7Zip in this instance, without having to extract the archive first. This is especially helpful when dealing with larger sized files.

  • Tells you where a command is in your $PATH, but also wether it's a link and to what.

    You may also use the $(which foo) variant instead of backticks. I personnaly have an alias ll='ls -l'. Show Sample Output

  • Sorted, recursive long file listing

    Tells you everything you could ever want to know about all files and subdirectories. Great for package creators. Totally secure too. On my Slackware box, this gets set upon login: LS_OPTIONS='-F -b -T 0 --color=auto' and alias ls='/bin/ls $LS_OPTIONS' which works great. Show Sample Output

    lsr() { find "${@:-.}" -print0 |sort -z |xargs -0 ls $LS_OPTIONS -dla; }

Run a command as root, with a delay
$ sleep 1h ; sudo command or $ sudo sleep 1h ; sudo command won't work, because by the time the delay is up, sudo will want your password again.

Notepad in a browser
A commandline version of the notepad in a browser: http://www.commandlinefu.com/commands/view/12161/notepad-in-a-browser-type-this-in-the-url-bar All credit to the origional author of this fantastic command, whos only failing as most of the comments pointed out was that it wasn't a command... well, now its a command.

Show a line when a "column" matchs

Find the biggest files
Show the top 10 file size

Query Wikipedia via console over DNS

Remove a line from a file using sed (useful for updating known SSH server keys when they change)
For example, to remove line 5 from foo, type: vi +5d +wq foo

Force machine to reboot no matter what (even if /sbin/shutdown is hanging)
This will cause your machine to INSTANTLY reboot. No un-mounting of drives or anything. Very handy when something has gone horribly wrong with your server in that co-location facility miles away with no remote hands! Suspect this works with all 2.2, 2.4 and 2.6 Linux kernels compiled with magic-syskey-request support.

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" }

Get absolut path to your bash-script
Another way of doing it that's a bit clearer. I'm a fan of readable code.

bulk rename files with sed, one-liner
Far from my favorite, but works in sh and with an old sed that doesn't support '-E'
