NAME
frombyte -- convert a byte stream files to MPE record files
SYNOPSIS
frombyte -b [bytestream_file] record_file
DESCRIPTION
The frombyte utility copies a byte stream file to an MPE record
file. It creates either a fixed-record 80-byte ASCII file (MPE
text file) or a fixed-record 120-word binary file. If bytes-
tream_file is omitted, frombyte reads from standard input.
If more flexibility is needed in file conversions, refer to the
description of FCOPY in the MPE/iX Reference Supplement
(32650-90353) or the FCOPY Reference Manual (32212-90003).
Options
-b creates a binary output file. If this option is not speci-
fied, the output is an ASCII file.
EXAMPLES
To convert a byte stream file to an MPE text file, use the fol-
lowing command:
frombyte /usr/src/zork.c zork.c.sys
The following example uses tar to create an archive of all files
in the /usr/src directory and pipes the archive through frombyte
to create an MPE binary file named tarfile.
tar -cvf - /usr/src | frombyte -b tarfile
DIAGNOSTICS
0 Successful completion.
1 An error occurred.
Messages
