Function Description: Filter control characters.

Grammar: col&http://www.aliyun.com/zixun/aggregation/37954.html ">NBSP;" [-BFX] [-l< Buffer Column number

Supplemental Note: In many UNIX documentation, there are RLF control characters. When we use the Shell special character ">" and ">>", the content of the description file is exported to the plain text file, the control character will become garbled, and the col instruction can filter the control characters effectively.

Parameters：
-B filters out all control characters, including Rlf and Hrlf.
-F Filters Rlf characters, but allows Hrlf characters to be rendered.
-X represents a jump character with more than one space character.
The number of-l< buffer columns > preset memory buffers have 128 columns, and you can specify the size of the buffer yourself.
