deleting lines with matching variable
 

I have a lists of emails that I need to delete.

e.g.

john@foo.com
jean@foo.com
mark@foo.com.cn

I need to remove the line that match the variable "foo.com". I have created a script but it also remove mark@foo.com.cn.

Any suggestions how to delete those lines matching foo.com without deleting foo.com.cz (or any characters after the given variables)

TIA

grep can do this nicely.

With this InFile ...
... this grep ...
... produced this OutFile...
The $ requires a comparison on foo.com at the end of the line.
The -v says keep the lines which do not match.

Grep or sed:


Please note I included @ just in case you have emails with domains such as moofoo.com

You could also do it all in bash with a simple loop. You would need to be clearer about the data:

1. Is is at the end of a line? otherwise Daniel's suggestion will not work

2. As pointed out by post above, is there a chance of a match on a sub name, like moofoo and foo

Lastly, when using variables in bash which may have any unusual characters, they should be quoted.

Yes. There might be a chance that this might happen. That is why I put "@" before the foo.com just to make sure it would not match moofoo.com

> 1. Is is at the end of a line? otherwise Daniel's suggestion will not work

I am not sure if I get it right but I assume yes because in my example, it is a lists of email address.

john@foo.com
jean@foo.com
mark@foo.com.cn

Looks like Daniel's suggestion works. Why I forgot the $ geezz
