NAME

File::Slurp::Remote - read/write files on remote systems using ssh.

SYNOPSIS

use File::Slurp::Remote;

write_remote_file($host, $file, @contents);

@lines = read_remote_file($host, $file);

$whole_thing = read_remote_file($host, $file);

# Log in as a different user on the remote system
$whole_thing = read_remote_file("$user\@$host", $file);

DESCRIPTION

This is similar to File::Slurp, but it reads and writes files on remote systems using ssh to get there.

If the remote user name is not the same as the local one, pass the host as user@host, just as you would to scp.

It uses ssh to get to the remote systems, through File::Slurp::Remote::SmartOpen. You can override the remote shell command by redefining $File::Slurp::Remote::SmartOpen::ssh.

$File::Slurp::Remote::scp is still defined for backwards compatibility, but it has never been used and setting it has no effect.

If the host is the local system (and no other user is given), the file is read or written directly, without ssh.

Files whose names end in .gz or .bz2 are decompressed as they are read and compressed as they are written.

As well as the functions below, everything that File::Slurp exports by default (read_file, write_file and so on) is exported.

FUNCTIONS

write_remote_file($host, $file, @contents)

Writes @contents to $file on $host, replacing anything already there. Returns nothing useful; it dies on failure.

read_remote_file($host, $file)

In list context, returns the lines of $file on $host, each with its line ending. In scalar context, returns the whole file as one string.

API SPECIFICATION

Input

Both functions take positional arguments:

$host     string, required.  A hostname, or user@host to log in as a
          different user.  The user name ends at the last '@'.
          Neither the user nor the host may be empty or begin with '-'.
$file     string, required.  The path on the remote system.
@contents list of strings (write_remote_file only).  Written in order,
          with no separator added.

Output

read_remote_file, list context:   list of strings, one per line
read_remote_file, scalar context: string
write_remote_file:                nothing useful

ERRORS

Both functions die if the host or user is invalid (see above), or if the file cannot be opened, written or closed. When ssh is used, a failure on the remote side is reported when the file is closed, so write_remote_file dies but read_remote_file may just return nothing.
