IPC::PerlSSH::Library::FS - a library of filesystem functions for
use IPC::PerlSSH; my $ips = IPC::PerlSSH->new( Host => "over.there" ); $ips->use_library( "FS", qw( mkdir chmod writefile ) ); $ips->call( "mkdir", "/tmp/testing" ); $ips->call( "chmod", 0600, "/tmp/testing" ); $ips->call( "writefile", "/tmp/testing/secret", <<EOF ); Some secret contents of my file here EOF
This module provides a library of functions for interating with the remote filesystem. It provides wrappers for most of the perl filesystem functions, and some useful new functions that are more convenient to call remotely.
Because of the large number of functions defined by this library, it is recommended to only load the ones being used by the program, to avoid sending unnecessary data when setting up SSH connections across slow links.
The following perl functions have trivial wrappers that take arguments and return values in the same way as perl's. They throw exceptions via the
IPC::PerlSSH call when they fail, rather than returning undef, because otherwise
$! would be difficult to obtain.
chown chmod lstat mkdir readlink rename rmdir stat symlink unlink utime
The following functions are imported from File::Path with the following API adjustments:
mkpath( $path, %opts ) # %opts supports mode, user, group rmtree( $path, %opts ) # %opts supports safe, keep_root
The following functions each returns just one element from the
stat() list for efficiency when only one is required.
stat_dev stat_ino stat_mode stat_nlink stat_uid stat_gid stat_rdev stat_size stat_atime stat_mtime stat_ctime stat_blksize stat_blocks
The following stored functions wrap the perl -X file tests (documented here in the same order as in perldoc perlfunc)
stat_readable stat_writable stat_executable stat_owned stat_real_readable stat_real_writable stat_real_executable stat_real_owned stat_exists stat_isempty stat_size stat_isfile stat_isdir stat_islink stat_ispipe stat_issocket stat_isblock stat_ischar stat_issetuid stat_issetgid stat_issticky stat_istext stat_isbinary stat_mtime_days stat_atime_days stat_ctime_days
The following functions are defined as variations on the perl function of the same name
my @ents = $ips->call( "readdir", $dirpath, $hidden );
Return a list of the directory entries. Hidden files are skipped if $hidden is true. . and .. are always skipped.
$ips->call( "remove", $path );
$path is a directory, or
unlink if not
The following functions are newly defined to wrap common perl idoms
my $content = $ips->call( "readfile", $filepath ); $ips->call( "writefile", $filepath, $newcontent );
To open a remote filehandle and interact with it over a sequence of multiple calls, see also IPC::PerlSSH::Library::IO.
