This displays the first 5 lines of all files starting with foo: head -n 5 foo* Most versions [citation needed] allow omitting n and instead directly specifying the number: -5.

Adverse impact on estimation: because of the fact presented under point #1, estimates based on lines of code can adversely go wrong, in all possibility. Developer's experience: implementation of a specific logic differs based on the level of experience of the developer. Hence, number of lines of code differs from person to person.
