Print line fragments according to the format string min. max, where min is the minimum field width and max the maximum field width. If min begins with a zero, zeros will be added to make up the field width, and if it begins with a -, the fragment will be left-adjusted within the field.
-p min. max
Like -f , but pad this files field when end-of-file is reached and other files are still active.
-s sepstring
Print sepstring before printing line fragments from the next file. This option may appear after the last file.
-t c
The input line terminator is c instead of a newline. The newline normally appended to each output line is omitted.
To print files simultaneously for easy viewing use pr(1).
