Commands using sort (800)
-
Often you need to find the files that are taking up the most disk space in order to free up space asap. This script can be run on the enitre filesystem as root or on a home directory to find the largest files. Show Sample Output
1find / -type f 2>/dev/null | xargs du 2>/dev/null | sort -n | tail -n 10 | cut -f 2 | xargs -n 1 du -h -
Greater than 500M and sorted by size.
1find . -type f -size +500M -exec du {} \; | sort -n -
1find / -type f -size +100M -exec du {} \; | sort -n | tail -10 | cut -f 2
-
This combines the above two command into one. Note that you can leave off the last two commands and simply run the command as "find /home/ -type f -exec du {} \; 2>/dev/null | sort -n | tail -n 10" The last two commands above just convert the output into human readable format.
1find /home/ -type f -exec du {} \; 2>/dev/null | sort -n | tail -n 10 | xargs -n 1 du -h 2>/dev/null -
1ps ax -L -o pid,tid,psr,pcpu,args | sort -nr -k4| head -15 | cut -c 1-90
-
1ps -e -orss=,args= | sort -b -k1,1n | pr -TW$COLUMNS
-
du -m option to not go across mounts (you usually want to run that command to find what to destroy in that partition) -a option to also list . files -k to display in kilobytes sort -n to sort in numerical order, biggest files last tail -10 to only display biggest 10
1du . -mak|sort -n|tail -10 -
1grep -o -h -rE '".*"' * | ispell -l -p ~/mydict | sort -u
-
Show the top 10 file size
1find -type f | xargs -I{} du -sk "{}" | sort -rn | head -
1seq -w 50 | sort -R | head -6 |fmt|tr " " "-"
-
Counts the frequency of words in a file Show Sample Output
1cat YOUR_FILE|tr -d '[:punct:]'|tr '[:upper:]' '[:lower:]'|tr -s ' ' '\n'|sort|uniq -c|sort -rn -
OpenVZ: Get disk quota usage for your VEID Show Sample Output
1vzlist -a -H -o hostname,diskspace,diskspace.s,veid | awk '{ printf( "%2.f%\t%s\t%s\n"), $2*100/$3, $4, $1}' | sort -r -
A shorter version Show Sample Output
1ls | grep -Eo "\..+" | sort -u -
1cat /backup/hd7/rdiff-log.txt |grep Processing | awk '{ print $4 }' | sed -e 's/\// /g' | awk '{ print $1 }' |uniq -c |sort -n
-
1find /path/to/dir -type f |sed 's/^.*\.//' |sort -f |uniq -i
-
If you're only using -m or -k, you will need to remember they are either in Megabyte or kilobyte forms. So by using -B, it gives you the unit of the size measurement, which helps you from reading the result faster. You can try with -B K as well. Show Sample Output
1du --max-depth=1 -B M |sort -rn -
Original: https://bugzilla.redhat.com/show_bug.cgi?id=194342
1cat /proc/mounts | awk '{print $2}' | grep "^$MOUNTPOINT" | sort -r | xargs umount -
Shows the full output of lsof.
1lsof | grep 'DEL.*lib' | sort -k1,1 -u -
We can get useful statistics from tcpdump with this simple command. Thanks "Babak Farrokhi" to teaching me this ;)
1tcpdump -nr capture.file | awk '{print }' | grep -oE '[0-9]{1,}.[0-9]{1,}.[0-9]{1,}.[0-9]{1,}' | sort | uniq -c | sort -n -
1netstat -n -f inet|awk '/\.389/{print $2}'|cut -f1-4 -d.|sort -u
-
Useful for checking the number and state of TCP connections. Show Sample Output
1netstat -nt | awk '{print $6}' | sort | uniq -c | sort -n -k 1 -r -
You can use any dictionary you want, in any language. This command will output all single-word annotations that you have underlined in your Kindle device (provided the file) given a list of language-specific words. If you want to learn vocabulary, this command is ideal.
1awk -F" " '{ if ( NF == 1 ) { print $0 } }' KINDLE_NOTES_FILE.txt | sed -e '/^=/d' | sed -e '/^[[:space:]]*$/d' -e 's/,//g' | sort | comm -12 List_of_language_words.txt - | uniq -
Evoke from the command like as:
timeDNS commandlinefu.com. This isn't too terribly practical, but it is a good code example of using subshells to run the queries in parallel and the use of an "anonymous function" (a/k/a "inline group") to group i/o. . I'm assuming you have already defined your local DNS cache as ${local_DNS}, (here, it's 192.168.0.1). . You do need to install `moreutils` to get `sponge`. . If you're willing to wait, a slower version w/o sponge, (and w/o sorting), is this: . DNS () { for x in "192.168.0.1" "208.67.222.222" "208.67.220.220" "198.153.192.1" "198.153.194.1" "156.154.70.1" "156.154.71.1" "8.8.8.8" "8.8.4.4"; do (echo -n "$x "; dig @"$x" "$*"|grep Query) ; done ; } Show Sample Output1timeDNS () { { for x in "${local_DNS}" "208.67.222.222" "208.67.220.220" "198.153.192.1" "198.153.194.1" "156.154.70.1" "156.154.71.1" "8.8.8.8" "8.8.4.4"; do ({ echo -n "$x "; dig @"$x" "$*"|grep Query ; }|sponge &) done ; } | sort -n -k5 ; } -
as per eightmillion's comment. Simply economical :)
1du -h | sort -hr -
creates associative array from apache logs, assumes "combined" log format or similar. replace awk column to suit needs. bandwidth per ip is also useful. have fun. I haven't found a more efficient way to do this as yet. sorry, FIXED TYPO: log file should obviously go after awk, which then pipes into sort.
1awk '{array[$1]++}END{ for (ip in array) print array[ip] " " ip}' <path/to/apache/*.log> | sort -n - ‹ First < 11 12 13 14 15 > Last ›
