skip

Skip part of a file.

As head will show the top of a file after a number of line, so skip will do the opposite, and not show the top of the file, but will show the rest.

Additionally, it can check for whole lines matching, or for a token being present on the line.

Usage

Skip a fixed number of lines

This example reads the file from stdin.

File: input.txt

line 1
line 2
line 3
line 4

skip 2 < input.txt

Will output:

line 3
line 4

Skip until a number of matching lines

This example reads the named file.

File: input.txt

alpha
beta
alpha
alpha
gamma
alpha

skip 2 --line alpha input.txt

Will output:

alpha
gamma
alpha

Skip lines until a number of tokens as seen

This example reads the file from stdin.

File: input.txt

Lorem ipsum dolor sit amet,

ut labore et dolore magna aliqua.

cat input.txt | skip 2 --token dolor

Will output:

Ut enim ad minim veniam, 
quis nostrud exercitation ullamco 
laboris nisi ut aliquip ex ea 
commodo consequat. 

It matches the first dolor on line 1, and the second on line 4 as part of the word dolore.
