The sort utility is well used, but sometimes you want a little chaos. This will randomize the lines of a text file.
BTW, on OS X there is no
| sort -R
option! There is also no
| shuf
These are only in the newer GNU core...
This is also faster than the alternate of:
| awk 'BEGIN { srand() } { print rand() "\t" $0 }' | sort -n | cut -f2-
Show Sample Output
on this way we can define the body too
If you're on a system that doesn't have nl, you can use cat -n.

Fast and excludes words with apostrophes. For ubuntu, you can use wamerican or wbritish dictionaries, installable through aptitude. Show Sample Output
this also can find the old command you used before
Cats a file in reverse. Show Sample Output
Where filein is the source file, destination.com is the ssh server im copying the file to, -c arcfour,blowfish-cbc is selecting the fastest encryption engines, -C is for online compressions and decompression when it comes off the line - supposed to speed up tx in some cases, then the /tmp/fileout is how the file is saved... I talk more about it on my site, where there is more room to talk about this: http://www.kossboss.com/linuxtarpvncssh and http://www.kossboss.com/linux---transfer-1-file-with-ssh Show Sample Output
Original command: cat "log" | grep "text to grep" | awk '{print $1}' | sort -n | uniq -c | sort -rn | head -n 100 This is a waste of multiple cats and greps, esp when awk is being used
Requires psc, sed, sc, and cat. Working with csv spreadsheets with formulas in them to evaluate the formulas using sc. View the formulas in a numbered and lettered formated in command line. function sheet () { cat "$1" | sed '1s/^/a,b,c,d,e,f,g,h,j,k,l,m,n,o,p\n/' | column -s , -tn | nl -v 0 ; }
IMPORTANT: You need Windows PowerShell to run this command - in your Windows Command Prompt, type
powershell
Uses sajb to start a PowerShell background job that pings an IP host every 10 seconds.
Any changes in the host's Up/Down state is time-stamped and logged to a file.
Date/time stamps are logged in two formats: Unix and human-readable.
A while(1) loop repeats the test every 10 seconds by using the sleep command.
See the Sample Output for more detail.
I use this command to log Up/Down events of my Motorola SB6141 cable modem (192.168.100.1).
To end the logging, close the PowerShell window or use the "exit" command.

It's not a big line, and it *may not* work for everybody, I guess it depends on the detail of access_log configuration in your httpd.conf. I use it as a prerotate command for logrotate in httpd section so it executes before access_log rotation, everyday at midnight.
Replaces tabs in output with spaces. Uses perl since sed seems to work differently across platforms.
Values will depend on the driver and the hardware specifics, so you need to refer to your driver documentation for proper interpretation of those values. Show Sample Output
the last person who posted used the most roundabout way to concatinate files, there's a reason there's a "conCATinate" command... Using this method, you also get to choose the order of the files, below another person just did *.txt > combined.txt which is fine but the order depends on the implementation of "cat" which is probably alphabetical order of filenames.

Count your source and header file's line numbers For example for java change the command like this find . -name '*.java' -exec cat {} \;|wc -l Show Sample Output
I know how hard it is to find an old command running through all the files because you couldn't remember for your life what it was. Heres the solution!! Grep the history for it. depending on how old the command you can head or tail or if you wanted to search all because you cannot think how long ago it was then miss out the middle part of the command. This is a very easy and effective way to find that command you are looking for.
