  • It works extremely fast, because it calculates md5sum only on the files that have the same size and name. But there is nothing for free - it won't find duplicates with the different names. Show Sample Output

    find -type f -printf '%20s\t%100f\t%p\n' | sort -n | uniq -Dw121 | awk -F'\t' '{print $3}' | xargs -d '\n' md5sum | uniq -Dw32 | cut -b 35- | xargs -d '\n' ls -lU

  • All the other example fail when running in a folder containing too many files due to * being saturated. This command does not use *, allowing me to run it in one folder containing over 300000 audio files. As to running on so many files, I used GNU parallel in order to spawn as many processes as cores, tremendously fasting up the process. Show Sample Output

    ls|grep ".wav"|parallel -j$(nproc) soxi -D {}|awk '{SUM += $1} END { printf "%d:%d:%d\n",SUM/3600,SUM%3600/60,SUM%60}'

  • ls -l outputs long listing of files to awk, which sorts the output to include all lines that have the executable bit set (-x.), but excludes (!) the lines that have the directory bit set (drw), then prints the results to the screen. Show Sample Output

    ls -l|awk ''/-x./' && !'/drw/' {print}'

  • Display recursive file list (newest file displayed at the end) and be free to access last file in the list simply by pressing arrow_up_key i.e. open it with joe editor. BTW IMHO the list of files with newest files at the end is often more informative. Put this 'lsa' function somewhere in your .bashrc and issue . ~/.bashrc or source ~/.bashrc to have access to the 'lsa' command immediately. . (the function appends command "joe last_file_in_the_list" at the end of command history)

    lsa() { ls -lart; history -s "joe \"$(\ls -apt|grep -v /|head -1)\"" ; }

  • This command will find any named file types in / between two dates then will list all the metadata of those files in long format and human readable form. Adding a 't' flag to the ls command sorts the files by modified time. After all that the head -5 lists the first 5 which can be changed.

    ls -laht `find / -name "*.*" -type f -newermt "2016-04-05" ! -newermt "2016-04-10"`|head -5

  • It will print a compact ls -la list with the directories at the beginning. --almost-all - do not list implied . and .. --group-directories-first - group directories before files --color - colorize the output --no-group - in a long listing, don't print group names --human-readable - print human readable sizes (e.g., 1K 234M 2G) --classify - append indicator (one of */=>@|) to entries If you want to see the owner: ls -l --almost-all --group-directories-first --color --no-group --human-readable --classify Show Sample Output

    ls -g --almost-all --group-directories-first --color --no-group --human-readable --classify

  • Grabs the first JSON file in the directory, reads its keys, prints TSV, then prints all the json files' values as TSV. Nested objects appear as json. Unhappy times if your json has literal tabs in it. Show Sample Output

    jq -r 'keys | join("\t")' $(ls -f *.json | head -1) && jq -Sr 'to_entries | [ .[] | .value | tostring ] | join("\t")' *.json

What's this? 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.

Recompress all files in current directory from gzip to bzip2
Find all .gz files and recompress them to bz2 on the fly. No temp files. edit: forgot the double quotes! jeez!

Generate a random password 30 characters long

Stop Flash from tracking everything you do.
Brute force way to block all LSO cookies on a Linux system with the non-free Flash browser plugin. Works just fine for my needs. Enjoy.

List files with full path
Prints contents of current directory with the full path prepended to each entry. You can add '-type f' if you don't want the directories to show up (for those less familiar with find). I can't believe ls doesn't have an option for this.

print all network interfaces' names and IPv4 addresses
ifconfig can't properly display interface's name longer 9 symbols,also it can't show IPs added thru ip command, so 'ip' should be used instead. This alias properly shows long names, bond interfaces and all interface aliases. loopback interface is ignored, since its IP is obvious

Change host name
With sed you can replace strings on the fly.

Find default gateway

Convert entire audio library in parallel
Uses parallel processing Reiteration of my earlier command Usage lc Old_Directory New_DIrectory Old_Format New_Format lc ~/Music ~/Music_ogg mp3 ogg

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" }

convert vdi to vmdk (virtualbox hard disk conversion to vmware hard disk format)
Converts a .vdi file to a .vmdk file for use in a vmware virtual machine. The benefit: using this method actually works. There are others out there that claim to give you a working .vmdk by simply using the qemu-img command alone. Doing that only results in pain for you because the .vmdk file will be created with no errors, but it won't boot either. Be advised that these conversions are very disk-intensive by nature; you are probably dealing with disk images several gigabytes in size. Once finished, the process of using the new .vmdk file is left as an exercise to the reader.
