Commands using sort (800)
-
This provides a way to sort output based on the length of the line, so that shorter lines appear before longer lines. It's an addon to the sort that I've wanted for years, sometimes it's very useful. Taken from my http://www.askapache.com/linux-unix/bash_profile-functions-advanced-shell.html Show Sample Output
2sortwc () { local L;while read -r L;do builtin printf "${#L}@%s\n" "$L";done|sort -n|sed -u 's/^[^@]*@//'; } -
2grep -Eo \([0-9]\{1,3\}[\.]\)\{3\}[0-9] file | sort | uniq
-
Extracts ip addressess from file using sed. Uses a tag(ip) to grep the IP lines after extracting. Must be a way to just output regex matched on sed. Show Sample Output
2sed -n 's/\([0-9]\{1,3\}\.\)\{3\}[0-9]\{1,3\}/\nip&\n/gp' ips.txt | grep ip | sed 's/ip//'| sort | uniq -
count the times a domain appears on a file which lines are URLs in the form http://domain/resource. Show Sample Output
2cut -d'/' -f3 file | sort | uniq -c -
find OGG audio files on your *nix box and listen to them using your web browser Show Sample Output
2echo '<html><body><table>' > /tmp/bar.html && find / -name '*.ogg' | sort | awk '{print "<tr><td>"$1"</td><td><audio src=\""$1"\" controls='controls'></audio></td></tr>" }' >> /tmp/bar.html && echo '</table></body></html>' >> /tmp/bar.html -
2history | awk '{a[$'$(echo "1 2 $HISTTIMEFORMAT" | wc -w)']++}END{for(i in a){print a[i] " " i}}' | sort -rn | head
-
The output is only partial because runtime dependencies should count in also commands executed via system() and libraries loaded with dlopen(), but at least it gives an idea of what a package directly links to. Note: this is meaningful *only* if you're using -Wl,--as-needed in your LDFLAGS, otherwise it'll bring you a bunch of false positives. Show Sample Output
2qlist --exact "$pkg" | sudo scanelf --needed --quiet --format '%n#F' | tr ',' '\n' | sort -u | qfile --from - -
Shows a list of users that currently running processes are executing as. YMMV regarding ps and it's many variants. For example, you might need:
ps -axgu | cut -f1 -d' ' | sort -uShow Sample Output2ps -eo user | sort -u -
2svn status | awk '{print $2}' | xargs du | sort -n | tail
-
2svn log 2>&1 | egrep '^r[0-9]+' | cut -d "|" -f2 | sort | uniq -c
-
Inspired by #7065
2ps -eorss,args | sort -nr | pr -TW$COLUMNS | head -
2find /etc/rc3.d/ | sort -g
-
2awk '{if ($1 ~ /Package/) p = $2; if ($1 ~ /Installed/) printf("%9d %s\n", $2, p)}' /var/lib/dpkg/status | sort -n | tail
-
list top committers (and number of their commits) of svn repository. in this example it counts revisions of current directory. Show Sample Output
2svn log -q | grep '^r[0-9]' | cut -f2 -d "|" | sort | uniq -c | sort -nr -
2echo $(shuf -n 6 -i 1-49 | sort -n)
-
Show disk space info, grepping out the uninteresting ones beginning with ^none while we're at it. The main point of this submission is the way it maintains the header row with the command grouping, by removing it from the pipeline before it gets fed into the sort command. (I'm surprised sort doesn't have an option to skip a header row, actually..) It took me a while to work out how to do this, I thought of it as I was drifting off to sleep last night! Show Sample Output
2df -h | grep -v ^none | ( read header ; echo "$header" ; sort -rn -k 5) -
Returns a the directory depth.
2find . -printf '%d\n' | sort -n | tail -1 -
List all MAC addresses on a Linux box. sort -u is useful when having virtual interfaces.
2sort -u < /sys/class/net/*/address -
Prints all the lines in /etc/passwd belonging to users with a duplicated uid. It also adds the hostname to the beginning of the line. It's been tested in AIX, Solaris and Linux. Show Sample Output
2awk -F: 'BEGIN{a[NULL]=0;dupli[NULL]=0;}{if($3 in a){print a[$3];print ;}else a[$3]=$0;} ' /etc/passwd | sort -t: -k3 -n | sed -e 's/^/'$(hostname)':/g' -
Specify the size in bytes using the 'c' option for the -size flag. The + sign reads as "bigger than". Then execute du on the list; sort in reverse mode and show the first 10 occurrences. Show Sample Output
2find /myfs -size +209715200c -exec du -m {} \; |sort -nr |head -10 -
Randomizes a file. The opposite of sort is sort -R!
2sort -R -
This command will allow to search for duplicate processes and sort them by their run count. Note that if there are same processes run by different users you'll see only one user in the result line, so you'll need to do:
ps aux | grep <process>to see all users that run this command. Show Sample Output2ps aux | sort --key=11 | uniq -c -d --skip-fields=10 | sort -nr --key=1,1 -
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'andalias ls='/bin/ls $LS_OPTIONS'which works great. Show Sample Output2lsr() { find "${@:-.}" -print0 |sort -z |xargs -0 ls $LS_OPTIONS -dla; } -
(separator = $IFS)
2ps aux | sort -nk 6 -
2grep "HTTP/1.1\" 404" access_log | awk '{print $7 } ' | sort | uniq -c | sort -n
- ‹ First < 7 8 9 10 11 > Last ›
