Simple SFTP commands

Pshell is a python command line client that implements a subset of the standard SFTP commands.

  • Remote filesystem commands: cd, ls, pwd, mkdir, rmdir
  • Local filesystem commands: lcd, lls, lpwd
  • Transfer commands: get, put 

Type help command to get information on the syntax of each.

Simple wildcards are accepted for file transfers.
There are also a few shell-like commands, such as:

  • whoami: reports the current logged in identity
  • file: reports metadata information on a file

Pagination

For file listings that are longer than the terminal height, a pagination control prompt will be displayed with the following options:

Entry

Result

<enter>Display the next page of files
<page number><enter>Display the requested page number
/<pattern>Filter the result on the pattern
qLeave (quit) paginated display mode
