Filesystem¶
-
pwd
() → String¶ Get the current working directory.
-
cd
(dir::String)¶ Set the current working directory.
-
cd
(f[, dir]) Temporarily changes the current working directory (HOME if not specified) and applies function f before returning.
-
mkdir
(path[, mode])¶ Make a new directory with name
path
and permissionsmode
.mode
defaults to 0o777, modified by the current file creation mask.
-
mkpath
(path[, mode])¶ Create all directories in the given
path
, with permissionsmode
.mode
defaults to 0o777, modified by the current file creation mask.
-
symlink
(target, link)¶ Creates a symbolic link to
target
with the namelink
.Note
This function raises an error under operating systems that do not support soft symbolic links, such as Windows XP.
-
chmod
(path, mode)¶ Change the permissions mode of
path
tomode
. Only integer modes (e.g. 0o777) are currently supported.
-
stat
(file)¶ Returns a structure whose fields contain information about the file. The fields of the structure are:
size The size (in bytes) of the file device ID of the device that contains the file inode The inode number of the file mode The protection mode of the file nlink The number of hard links to the file uid The user id of the owner of the file gid The group id of the file owner rdev If this file refers to a device, the ID of the device it refers to blksize The file-system preffered block size for the file blocks The number of such blocks allocated mtime Unix timestamp of when the file was last modified ctime Unix timestamp of when the file was created
-
lstat
(file)¶ Like stat, but for symbolic links gets the info for the link itself rather than the file it refers to. This function must be called on a file path rather than a file object or a file descriptor.
-
ctime
(file)¶ Equivalent to stat(file).ctime
-
mtime
(file)¶ Equivalent to stat(file).mtime
-
filemode
(file)¶ Equivalent to stat(file).mode
-
filesize
(path...)¶ Equivalent to stat(file).size
-
uperm
(file)¶ Gets the permissions of the owner of the file as a bitfield of
01 Execute Permission 02 Write Permission 04 Read Permission For allowed arguments, see
stat
.
-
gperm
(file)¶ Like uperm but gets the permissions of the group owning the file
-
operm
(file)¶ Like uperm but gets the permissions for people who neither own the file nor are a member of the group owning the file
-
cp
(src::String, dst::String)¶ Copy a file from src to dest.
-
download
(url[, localfile])¶ Download a file from the given url, optionally renaming it to the given local file name. Note that this function relies on the availability of external tools such as
curl
,wget
orfetch
to download the file and is provided for convenience. For production use or situations in which more options are need, please use a package that provides the desired functionality instead.
-
mv
(src::String, dst::String)¶ Move a file from src to dst.
-
rm
(path::String; recursive=false)¶ Delete the file, link, or empty directory at the given path. If
recursive=true
is passed and the path is a directory, then all contents are removed recursively.
-
touch
(path::String)¶ Update the last-modified timestamp on a file to the current time.
-
tempname
()¶ Generate a unique temporary file path.
-
tempdir
()¶ Obtain the path of a temporary directory (possibly shared with other processes).
-
mktemp
()¶ Returns
(path, io)
, wherepath
is the path of a new temporary file andio
is an open file object for this path.
-
mktempdir
()¶ Create a temporary directory and return its path.
-
isblockdev
(path) → Bool¶ Returns
true
ifpath

true
ifpath
is a directory,false
otherwise.
-
isexecutable

,false
otherwise.
-
isfifo
(path) → Bool¶ Returns
true
ifpath
is a FIFO,false
otherwise.
-
isfile
(path) → Bool¶ Returns
true
ifpath
is a regular file,false
otherwise.
-
islink
(path) → Bool¶ Returns
true
ifpath
is a symbolic link,false
otherwise.
-
ispath
(path) → Bool¶ Returns
true
ifpath
is a valid filesystem path,false
otherwise.
-
isreadable
(path) → Bool¶ Returns
true
if the current user has permission to readpath
,false
otherwise.
-
issetgid
(path) → Bool¶ Returns
true
ifpath
has the setgid flag set,false
otherwise.
-
issetuid
(path) → Bool¶ Returns
true
ifpath
has the setuid flag set,false
otherwise.
-
issocket
(path) → Bool¶ Returns
true
ifpath
is a socket,false
otherwise.
-
issticky
(path) → Bool¶ Returns
true
ifpath
has the sticky bit set,false
otherwise.
-
iswritable
(path) → Bool¶ Returns

-
homedir
() → String¶ Return the current user’s home directory.
-
dirname

expands to a string with the absolute path and file name of the script being run. Returnsnothing
if run from a REPL or an empty string if evaluated byjulia -e <expr>
.
-
isabspath
(path::String) → Bool¶ Determines whether a path is absolute (begins at the root directory).
-
isdirpath
(path::String) → Bool¶ Determines whether a path refers to a directory (for example, ends with a path separator).
-
joinpath
(parts...) → String¶ Join path components into a full path. If some argument is an absolute path, then prior components are dropped.
-
abspath
(path::String) → String¶ Convert a path to an absolute path by adding the current directory if necessary.
-
normpath

-
splitdir
(path::String) -> (String, String)¶ Split a path into a tuple of the directory name and file name.
-
splitdrive
(path::String) -> (String, String)¶ On Windows, split a path into the drive letter part and the path part. On Unix systems, the first component is always the empty string.
-
splitext
(path::String) -> (String, String)¶ If the last component of a path contains a dot, split the path into everything before the dot and everything including and after the dot. Otherwise, return a tuple of the argument unmodified and the empty string.
