equivalent of ftp put and append in scp

问题:

I have a legacy script which I am not able to understand.

The script is to transfer 4 files (2 ebcdic format files and 2 pdf files) in unix to mainframes through ftp.

ebcdic format file 1 is abc.xyz
ebcdic format file 2 is pqr.xyz
pdf file 1 is abc.pdf
pdf file 2 is pqr.pdf
mainframe file name is AM2P.BJCUN.SALCHG

The syntax of the command in the script is as below:

quote site recfm=fb
put /myfiles/abc.xyz AM2P.BJCUN.SALCHG
append /myfiles/abc.pdf AM2P.BJCUN.SALCHG
append /myfiles/pqr.xyz AM2P.BJCUN.SALCHG
append /myfiles/pqr.pdf AM2P.BJCUN.SALCHG

I want to achieve the same thing through SCP.

Could someone please tell what is the equivalent of put and append command of ftp in scp ??

回答1:

Put is just the normal scp

scp /path/to/source user@host:/path/to/target

Append only works with a little hack (and not with scp directly)

cat source | ssh user@host "cat >> /path/to/target"

回答2:

scp can not append (ssh can, but it is not always an option). You can copy remote file, append it locally and then put it back.
