I want to display a line matching a search term and all the remaining lines in the file.
For example, if I use:
more text.txt | egrep show
it will only show the line that has "show" in it, while I would wish for something like a start
command:
more text.txt | start show
that will show all the lines after the first line that matches the search term.
However, it's not working on my Ubuntu. How can I install it or anything similar to it?

If your file is less than, say, 10000 lines, you can do this:
The
-A
flag will show the line containing the search string (show
) and the next 10000 lines.However, I played around with the
-A
flag a bit, and I noticedgrep
will intelligently combine the output, so you don't get 10001 lines for each time the stringshow
is found. So basically, it will show you the whole file once, starting from the line that containsshow
. If your file contains more than 10000 lines, adjust the parameter appropriately.You can use the
alias
command to create your own custom command to achieve the same result.EDIT: a slightly more elegant solution would be to use
which will use the actual length of the file as the
-A
flag. This requires you to specify the file name twice. Unfortunately this will prevent the use of an alias, but you could write a shell function to do this.Apparently, in this case you need to specify the search string first to avoid an error.
