Create your handy commands in Linux

Creating commands in linux is as simple as having your meal when you are hungry.


Now let us consider an example.


I have screen scrapped a webpage for analyzing the results. It consists of much complex mix up of linux commands.


Website: http://www.espncricinfo.com/australia-v-india-2011/engine/match/518950.html


I can run them as a single command by using the concept of piping, but for simplicity I split them as two commands. The result of first command will be stored in a temporary file, which will be given as input to second command.




curl http://www.espncricinfo.com/australia-v-india-2011/engine/match/518950.html>/home/jophine/out


grep 'colspan="2">A\|colspan="2">I\|width="19\|width="25\|<td class="b' /home/jophine/out|sed 's/.*colspan=\"2\">\([AI].*\)<span.*/\1/g'|sed 's/.*width=\"19.*playerName\">\(.*\)<\/a>.*/\1/g'|sed 's/.*width=\"25.*battingDismissal\">\(.*\)<\/td>/\1/g'|sed 's/<td class=\"\(.*\)\">\(.*\)<\/td>/\1\t\2/g'|sed 's/battingRuns\">\([0-9]*\)<\/td>.*/battingRuns\t\t\1/'|sed 's/bowlingDetails\".*//'

Now I don't need the out(temporary file) anymore, so i'll remove it,

rm /home/jophine/out

(I am using full path because it is safe to create temporary file in your home directory)


Now, i'll club the three commands in a single file named cricinfo

But this is just a text file, to make it executable, 

in the first line give the compiler / interpreter path with which you use to execute your code. This is a shell script now so i'll provide the path as follows,

#!/bin/bash (shebang) for perl it may be #!/usr/bin/perl it all depends on the name of interpreter and path.

Now my file will looks like this:

#!/bin/bash

curl http://www.espncricinfo.com/australia-v-india-2011/engine/match/518950.html>/home/jophine/out

grep 'colspan="2">A\|colspan="2">I\|width="19\|width="25\|<td class="b' /home/jophine/out|sed 's/.*colspan=\"2\">\([AI].*\)<span.*/\1/g'|sed 's/.*width=\"19.*playerName\">\(.*\)<\/a>.*/\1/g'|sed 's/.*width=\"25.*battingDismissal\">\(.*\)<\/td>/\1/g'|sed 's/<td class=\"\(.*\)\">\(.*\)<\/td>/\1\t\2/g'|sed 's/battingRuns\">\([0-9]*\)<\/td>.*/battingRuns\t\t\1/'|sed 's/bowlingDetails\".*//'

rm /home/jophine/out

Save the file and use the following command in terminal:

chmod u+x cricinfo

Now you can run the executable by typing ./cricinfo in the terminal.

But how to use it as a command...?

Very simple, run which ls command in terminal. This will produce a path probably "/bin/ls"

Now copy the file to the above path cp cricinfo /bin/cricinfo.

Bull shit!! (sorry) I need to be a root for that purpose, to become root, type sudo su - and give sudo password

Now do the copy cp cricinfo /bin/cricinfo
Navigate to /bin cd /bin then change the ownership of the file sudo chown jophine cricinfo

From the moment copy is successful you can use cricinfo as a command form any path.


This is just an example, you can automate any frequent tasks as an executable and use it as command as well.

Yes boss I got your mind voice...

Let me execute the command...
