This article will explain in detail about the use of linux's colrm command to filter the specified columns. The editor thinks it is very practical, so I share it with you for reference. I hope you can get something after reading this article.

The English full name of the colrm command is "column remove", which means to delete a column. The function is to read data from a standard input device and then output it to a standard output device. If no parameters are added, the instruction will not filter any column.

Syntax format: colrm [starting column number]

Common parameters:

The starting column number specifies the starting number of the column to be deleted and the end column number of the column to be deleted. Sometimes this parameter can be omitted.

Reference example

Delete everything after column 4:

[root@linuxcool ~] # colrm 4

Delete columns 4 through 6:

[root@linuxcool ~] # colrm 46 about using linux's colrm command to filter specified columns is shared here. I hope the above content can be helpful to everyone and learn more knowledge. If you think the article is good, you can share it for more people to see.
