Hello, when I ran the following, it produces standard output and not a file. Any idea whats goin on here or is my syntax not correct.

uuencode -m test test1.

UUEncode will always put it's output onto STDOUT.

The reason for the two filenames is for input, and what is encoded into the output.

For example, lets look at the headers involved:

[bekar@elfgrove tmp]$ uuencode data test.txt
begin 644 test.txt
.... encoded data here ...

And with '-m':

[bekar@elfgrove tmp]$ uuencode -m data test.txt
begin-base64 644 test.txt
... encoded data here ...

The idea is you redirect (using >) or pipe (|) the ouput of UUEncode to another application or file.

UUDecode on the other hand will take a filename (or data-stream/pipe), and output a file based on the name on the 'begin' line of the encoded data. This can be overridden with the '-o' flag. This is only available on the UUDECODE application.

hi,
uuencode writes to standard output. If you want it to write to test1:
uuencode -m test > test1

I have a binary file that I am trying to convert to ASCII. I played with uuencode but can't create any file with it.

I tried teh other suggestion with re-direct > but that doesn't work.

I'm not sure in this event that uuencode is the best tool to use. Maybe, but these commands might help depending on what kind of file it is.

Consider the following commands:

dos2unix

unix2dos(1) mac2unix(1)

So what you want to do is this:

uuencode -m binfile binfile > file.uuencode

Then transfer 'file.uuencode' to the remote machine, and then:

uudecode file.uuencode

This will extract 'binfile'.

Hi Sanjit,
If you want to grab ascii out of a binary, you can use the strings command:

strings binfile > ascifile

Is this what you want to do ?
