  • Determine whether a CPU has 64 bit capability or not

    Check if you have 64bit by looking for "lm" in cpuinfo. lm stands for "long mem". This can also be used without being root.

    if cat /proc/cpuinfo | grep " lm " &> /dev/null; then echo "Got 64bit" ; fi

  • To get the CPU temperature continuously on the desktop

    There is no need for variables. I also added sleep to reduce cpu usage, however I didn't test it.

  • Fastest Sort. Sort Faster, Max Speed

    sort is way slow by default. This tells sort to use a buffer equal to half of the available free memory. It also will use multiple process for the sort equal to the number of cpus on your machine (if greater than 1). For me, it is magnitudes faster. If you put this in your bash_profile or startup file, it will be set correctly when bash is started. sort -S1 --parallel=2 <(echo) &>/dev/null && alias sortfast='sort -S$(($(sed '\''/MemF/!d;s/[^0-9]*//g'\'' /proc/meminfo)/2048)) $([ `nproc` -gt 1 ]&&echo -n --parallel=`nproc`)' Alternative echo|sort -S10M --parallel=2 &>/dev/null && alias sortfast="command sort -S$(($(sed '/MemT/!d;s/[^0-9]*//g' /proc/meminfo)/1024-200)) --parallel=$(($(command grep -c ^proc /proc/cpuinfo)*2))" Show Sample Output

    alias sortfast='sort -S$(($(sed '\''/MemF/!d;s/[^0-9]*//g'\'' /proc/meminfo)/2048)) $([ `nproc` -gt 1 ]&&echo -n --parallel=`nproc`)'

  • Calculates the number of physical cores considering HyperThreading in AWK

    Check whether hyperthreading is enabled or not. a better solution as nproc should work on all OS with awk Show Sample Output


    2
    awk -F: '/^core id/ && !P[$2] { CORES++; P[$2]=1 }; /^physical id/ && !N[$2] { CPUs++; N[$2]=1 }; END { print CPUs*CORES }' /proc/cpuinfo

    No need for a colon, and one less semicolon too. Also untested.

  • Shows cpu load in percent

    This version is precise and requires one second to collect statistics. Check sample output for a more generic version and also a remote computer invocation variant. It doesn't work with the busybox version of the 'top' command but can be adjusted Show Sample Output

    top -bn2|awk -F, '/Cpu/{if (NR>4){print 100-gensub(/.([^ ]+).*/,"\\1","g",$4)}}'

What's this?

commandlinefu.com 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.

Check These Out

Count lines of code across multiple file types, sorted by least amount of code to greatest
The same as the other two alternatives, but now less forking! Instead of using '\;' to mark the end of an -exec command in GNU find, you can simply use '+' and it'll run the command only once with all the files as arguments. This has two benefits over the xargs version: it's easier to read and spaces in the filesnames work automatically (no -print0). [Oh, and there's one less fork, if you care about such things. But, then again, one is equal to zero for sufficiently large values of zero.]

Substitute an already running command
eg: Already running cmd $sleep 120 Substitution cmd $c=$(pgrep sleep) && sleep 5 && kill $c

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" }

Generate random valid mac addresses
Doubt it actually generates valid mac addresses but this version doesn't need any external commands so it runs much faster. Much shorter as well.

formatting number with comma
it is not work with Cygwin's bash3.X. Test in Linux. use printf "%'f" number while it is floating point number

Resume aborted scp file transfers
Put it into your sh startup script (I use alias scpresume='rsync --partial --progress --rsh=ssh' in bash). When a file transfer via scp has aborted, just use scpresume instead of scp and rsync will copy only the parts of the file that haven't yet been transmitted.

Backup with versioning
Apart from an exact copy of your recent contents, also keep all earlier versions of files and folders that were modified or deleted. Inspired by EVACopy http://evacopy.sourceforge.net

Have a random "cow" say a random thing
You need to have fortune and cowsay installed. It uses a subshell to list cow files in you cow directory (this folder is default for debian based systems, others might use another folder). you can add it to your .bashrc file to have it great you with something interesting every time you start a new session.

Plays Music from SomaFM
This command asks for the station name and then connects to somafm, Great for those who have linux home entertainment boxes and ssh enabled on them, just for the CLI fiends out there ( I know I'm one of them ;) Also, don't forget to add this as alias(ie alias somafm="read -p 'Which Station? "; mplayer --reallyquite -vo none -ao sdl http://somafm.com/startstream=${REPLY}.pls")
