printf - format and print data
printf FORMAT [ARGUMENT]...
Print ARGUMENT(s) according to FORMAT, or execute according to OPTION:
FORMAT controls the output as in C printf. Interpreted sequences are:
- double quote
- alert (BEL)
- produce no further output
- form feed
- new line
- carriage return
- horizontal tab
- vertical tab
- byte with octal value NNN (1 to 3 digits)
- byte with hexadecimal value HH (1 to 2 digits)
- Unicode (ISO/IEC 10646) character with hex value HHHH (4 digits)
- Unicode character with hex value HHHHHHHH (8 digits)
- a single %
- ARGUMENT as a string with '\' escapes interpreted, except that octal escapes are of the form \0 or \0NNN
- ARGUMENT is printed in a format that can be reused as shell input, escaping non-printable characters with the proposed POSIX $'' syntax.
and all C format specifications ending with one of diouxXfeEgGcs, with ARGUMENTs converted to proper type first. Variable widths are handled.
NOTE: your shell may have its own version of printf, which usually supersedes the version described here. Please refer to your shell's documentation for details about the options it supports.
