Common commands for the shell

Sort

Handle sorting problems.

For example: Sort-r/file the rows of file in descending order.

Tr:

As a simplified version of SED, you can replace another character with one character, or delete some characters.

Cut

Splitting according to the line of the file is a selection command that splits what we want.

For example: Cat/etc/passwd|cut-b 1-5 takes the 1th to 5th bytes of each row.

Paste

Merging multiple file contents is just the opposite of what the Cut command does.

For example: Create File1, write content aaa, create file2, write content bbb paste-d: file2 file1 get: bbbaaa

Uniq

Filter the repeating section to display the file contents.

Tee

Redirect output to screen and file.

Wc:

The number of words in the statistics file, how many lines, how many characters.
