I have logged on to a system with ssh and there is no scp present on both the systems. How to copy a file without using the scp program.

To send a file:
cat file | ssh ajw@dogmatix "cat > remote"
Or:
ssh ajw@dogmatix "cat > remote" < file
To receive a file:
ssh ajw@dogmatix "cat remote" > copy

21@ggg that's not true at all.
cd /tmp; cat /bin/bash > test; chmod a+x test; diff test /bin/bash; ./testall works fine. There's nothing inherently "magic" about binary files. Both files in my example compared identical and have the same checksum. It's true that copy and pasting from a terminal window won't work because of things like control sequences and unprintable characters, but using pipes like this these never go near a terminal.

@Flexo I need something like this, the only exception is, I need to pipe in all jpg from a folder. How could iterate through /storage/sdcard1/*jpg and

3@GeorgeProfenza you'll need to add
tarinto the mix.tar cvf - /path/*.jpg | ssh [email protected] "tar xvf -"or something similar ought to work. Commented Jul 3, 2013 at 20:36 -
One implication of what ggg and Flexo say above is that you can't use the "-t" option to ssh.– mjg123Commented Nov 5, 2014 at 13:43

1Nice! You can also use pv instead of the first cat so you get a progressbar, eg
pv file | ssh ajw@dogmatix "cat > remote"Commented May 18, 2018 at 9:14
Try this:
cat myfile.txt | ssh me@otherhost 'cat - > myfile.txt'

1@RenanWillianPrado It tells
catspecifically to read from stdin. Mostly useful to concatenate stdin after another file.– KeithCommented Apr 8, 2022 at 9:30
You can use xxd and some ugly quoting to copy over multiple files as well as run commands on them and execute them:
ssh -t [email protected] "
echo $'"$(cat somefile | xxd -ps)"' | xxd -ps -r > "'somefile'"
chmod +x somefile
echo $'"$(cat someotherfile | xxd -ps)"' | xxd -ps -r > "'someotherfile'"
chmod +x someotherfile
./somefile
./someotherfile
"
Besides piping the file to a remote cat, you may also be able to use some SFTP client to transfer the files.

+1 but it should be noted that the OP is attempting to avoid scp because it does not exist on the systems. Given this constraint it's also probable that an FTP server needs to exist on the receiving end which makes the copying process dependent on software other than what is usually there by default.

python3 -m http.server in the same directory with desired file - after that you can curl or wget or download a file with your browser. Note that with that running command all your files from current directory will be publicly available, until you press Ctrl+C.

rsync?ssh user@remotehost cat /path/to/remote/file > /path/to/local/file
