glxshell.utilities.tail module¶

glxshell.utilities.tail.glxsh_tail(c, f, n, files)[source]¶

The tail utility shall copy its input file to the standard output beginning at a designated place.

Copying shall begin at the point in the file indicated by the -c number or -n number options. The option-argument number shall be counted in units of lines or bytes, according to the options -n and -c. Both line and byte counts start from 1.

Tails relative to the end of the file may be saved in an internal buffer, and thus may be limited in length. Such a buffer, if any, shall be no smaller than {LINE_MAX}*10 bytes.

Parameters:

files (list or None) – A pathname of an input file. If no file operand is specified, the standard input shall be used.
