String alterations.

Hello Everyone,

I am relatively new to shell scripting.

I wish to simply do the following, take a string.

such as

"/folder/folder1/folder2 --skip_thingy --ps_name random --something"

and remove "--ps_name" (which is always the string I will "look" for) and whatever sting immediately after it, in this case "random".

So i am left with

"/folder/folder1/folder2 --skip_thingy --something"

Also keeping in mind that the order of the string, and string length could change.

So again,

Start here;
"/folderx/foldery/folderz --something3 --skip_thingy --ps_name random"

End here;

"/folderx/foldery/folderz --something3 --skip_thingy"

Any help would be appreciated!

Thanks Smilie
Ash

Awesome. Guess learning perl would be also something I should look in to :P

Thanks for the help!

You can also do something like:
Code:
sed 's/--ps_name [^ ]* *//'
