使用-f 选项，打印文本的列，例如打印文本的第一列内容，使用-f 1。[root@server-01 ~]# cut -f 1 /etc/passwdroot:x:0:0:root:/root:/bin/bashbin:x:1:1:bin:/bin:/sbin/nologindaemon:x:2:2:daemon:/sbin:/sbin/nologinadm:x:3:4:adm:/var/adm:/sbin/nologinlp:x:4:7:lp:/var/spo...

Cut breaks up a line and takes out the text in it. It is mandatory to provide the options while writing the command; otherwise it will throw an error. If we operate on multiple files by providing more than one file name, then data from both files will not be preceded by its name. ...

For example 2nd column from file1 and 3rd column from file2. Obviously with the power of thebashshell you can do stuff like: but that requires too much typing (3 commands, using SHIFTs on the keyboard, & shell-magic), while still not supporting regexp-style delimiters and offsets from ...
To repeat: the meaning of each character depends on the entire contents of the file up to that point. This has two negative consequences. CSV files must beparsed sequentiallyfrom start to end. They cannot be split up and processed in parallel (without first scanning them to make sure the ...
