I have a file of form
foo.txt
id, some_string, stringy_string..
and so on
How do I find a particular id in this foo.txt
This id will/should be present in just one line. (i.e no multiple instances?)
Thanks
It depends on how the id’s look like. If they do not contain any grep special characters, you can use
The
^matches the beginning of the line, the comma just makes sure the id ends there (soid12is not matched inid123).You have to escape special characters if they can appear in the id.
