The cat command (short for concatenate) is used to read plain text files. It's similar to the "type" command in DOS. The basic usage is cat file, where "file" is the name of the file you want to read.
Example:| $ cat FILE ←Read the contents of a file $ cat -n FILE ←Read the contents of a file with line numbers $ cat FILE1 FILE2 > FILE3 ←Combine two text files (FILE1/FILE2) into one file (FILE3) |
