- NAME
-
- gremlin - copy input to output flipping bits.
-
- SYNOPSIS
-
- gremlin [-dn] [<file] [>file]
-
- DESCRIPTION
-
- Gremlin copies its input to its output flipping bits at
- random. The interbit distance is uniformly distributed over
- the interbit distance parameter specified with the option -d.
- The default interbit distance is 64 so that, on the average,
- every 32nd bit is flipped when viewing the input as a bit
- stream.
-
- The options are;
-
- # Provokes display of 'Usage:' message.
-
- ! Provokes display of copyright notice.
-
- -dn Set interbit distance to integer n. (Default is 64)
-
- EXAMPLES
-
- gremlin <text
-
- Read file TEXT and display corrupted output to console. The
- default interbit distance is 64.
-
- gremlin -d120 >count
-
- Read from console until an empty line is entered and
- output corrupted text to file COUNT. On the average each
- 60th bit is flipped.
-
- gremlin
-
- Read the console line by line and echo the corrupted input.
-
- DIAGNOSTICS
-
- Unable to Open ??? for Input.
- Unable to Open ??? for Output
- Produced by file not found or, maybe, disk full?
-
- Error: Invalid interbit distance.
- The specified interbit distance is less than 1.
