  • Thanks to the authors of: awk '!x[$0]++' <file> and the author of: joinargs() { (local IFS="$1"; shift && echo "$*") } and others, we can have a fast Linux or android. IMPORTANT if you find a priority order problem in PATH you can push a path directory to the front without duplication as follows: PATH=/bin:$PATH then ... Check duplication with: echo $PATH|tr : '\n'|sort|uniq -d Finally do a very neat line by line list of $PATH: echo "${PATH//:/$'\n'} The speed up is very noticeable for android, and builds on Linux Ubantu are much faster with make and scripts. I will update the command on request. Timothy from SONY

    glu() { (local IFS="$1"; shift && echo "$*") }; repath() { ( _E=`echo "${PATH//:/$'\n'}" | awk '!x[$0]++'`; glu ":" $_E ) ; } ; PATH=`repath` ; export PATH

  • Axel --max-speed=x, -s x You can specify a speed (bytes per second) here and Axel will try to keep the average speed around this speed. Useful if you don?t want the program to suck up all of your bandwidth.

    axel --max-speed=x

  • We don't use CPU scaling, but just in case you do, there is something interesting to note. If you look at the /proc/cpuinfo, the speed listed is current running speed of the processors and not the real speed of the chip. Show Sample Output

    awk -F": " '/cpu MHz\ */ { print "Processor (or core) running speed is: " $2 }' /proc/cpuinfo ; dmidecode | awk -F": " '/Current Speed/ { print "Processor real speed is: " $2 }'

  • All output is placed in file SHA1SUMS which you can later check with 'sha1sum --check'. Works on most Linux distros where 'sha1sum' is installed.

    find . -type f -exec sha1sum {} >> SHA1SUMS \;

What Others Think

This command also works by simply using: -t17 rather than: --type 17
