Find lines starting with one specific character and ending with another one

Question:

I need to find a line in a file that starts with an <strong>a</strong> and the last word in the line ends with an <strong>e</strong>.

How can I do it with a tool like grep?

Answer1:

Just say this:

grep '^a.*e$' file

This means: look for those lines starting (^) with a, then 0 or more characters and finally and e at the end of the line ($).

<h3>Test</h3> $ cat a hello and thisfinishes with e foo $ grep '^a.*e$' a and thisfinishes with e

Answer2:

Simple answer : use grep.

grep -E "^a.*e$" filename

the ^ indicates the beggining of the line the $ marks the end of the line the .* means any character (the .) repeated from zero to any number of times (the *).
