Commands using ls (518)
-
0find / \( -mount -o -prune \) \( -perm -4000 -o -perm -2000 \) -type f -exec ls -l {} \;
-
Returns a list, with attributes (think `ls -l`), in reverse chronological order. N is a single numeric parameter. Robust against unfriendly filenames and directory structures. Show Sample Output
0nmf() { find . -type f -printf '%T@ ' -print0 -printf '\n' | sort -rn | head -"$1" | cut -f2- -d" " | tr -d "\0" | tr "\n" "\0" | xargs -0 ls -Ulh; } -
I've shortened it to:
lsc PATH | l... by adding ...alias lsc="ls --color"... and ...alias l="less -R"... to my ~/.bashrc file0ls --color PATH | less -R -
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
0jq -r 'keys | join("\t")' $(ls -f *.json | head -1) && jq -Sr 'to_entries | [ .[] | .value | tostring ] | join("\t")' *.json -
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 --classifyShow Sample Output0ls -g --almost-all --group-directories-first --color --no-group --human-readable --classify -
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.
0ls -laht `find / -name "*.*" -type f -newermt "2016-04-05" ! -newermt "2016-04-10"`|head -5 -
0ls -l --color | less -R
-
0man $(ls /bin | shuf -n1)
-
Pipes the output of ls to espeak Also works nice with fortune

I seem to do this compulsively every time I change directories, sometimes even when I don't, even if I know exactly what I need to do. (Don't worry, the sample output is just an exaggeration. :) Show Sample Output
0grep -cx ls ~/.bash_history -
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
0ls -l|awk ''/-x./' && !'/drw/' {print}' -
0find . -mtime +30 -exec ls -all "{}" \; | awk '{COUNTER+=$5} END {SIZE=COUNTER/1024/1024; print "size sum of found files is: " SIZE "MB"}'
-
Resume incomplete youtube-dl video files. Assuming mp4 format here.
0ls *.part | sed 's/^.*-\(.\{11,11\}\)\.mp4\.part$/\1/g' - | youtube-dl -i -f mp4 -a - -
All the other example fail when running in a folder containing too many files due to * being saturated. This command does not use *, allowing me to run it in one folder containing over 300000 audio files. As to running on so many files, I used GNU parallel in order to spawn as many processes as cores, tremendously fasting up the process. Show Sample Output
0ls|grep ".wav"|parallel -j$(nproc) soxi -D {}|awk '{SUM += $1} END { printf "%d:%d:%d\n",SUM/3600,SUM%3600/60,SUM%60}' -
0ls -t /mcdata/archive/learn/backup-moodle2-course-* | tail -n +11 | xargs -I {} rm {}
-
Show file count into directories. Usefull when you try to find hugh directories that elevate system CPU (vmstat -> sy) Show Sample Output
0find / -type d | while read i; do ls $i | wc -l | tr -d \\n; echo " -> $i"; done | sort -n -
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
0find -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 -
0find . -name '*.log' | xargs ls -hlt > /tmp/logs.txt && vi /tmp/logs.txt
-
0AWS_DEFAULT_REGION="sa-east-1" jungle ec2 ls | grep midas | sort | cut -f4 | xargs -I {} ssh ubuntu@{} sudo apt-get install ntp -y

I couldn't find movie library on any of the SQLlite Stremio databases, but on ~/.config/stremio/backgrounds2 the background image filenames corresponds to IMDB URL. So I foreach files and wget HTML title of each movie and save it to a file. This will retrieve all movie names, not just the Library.
0time for movie in $(ls -1 $HOME/.config/stremio/backgrounds2 | sort -u);do echo "https://www.imdb.com/title/$movie/" | wget -qO- -O- -i- --header="Accept-Language: en" | hxclean | hxselect -s '\n' -c 'title' 2>/dev/null | tee -a ~/movie-list.txt ; done -
On Linux, use watch -n 1 ls path/to/dir H/t: https://stackoverflow.com/a/9574123/805405 Show Sample Output
0while :; do clear; ls path/to/dir | wc -l; sleep 1; done -
find all files that have 20 or more MB on every filesystem, change the size and filesystem to your liking
0find / -type f -size +20000k -exec ls -lh {} \; 2> /dev/null | awk '{ print $NF ": " $5 }' | sort -nrk 2,2 -
