'%alias alias_name cmd' defines 'alias_name' as an alias for 'cmd' Then, typing 'alias_name params' will execute the system command 'cmd params' (from your underlying operating system). Aliases have lower precedence than magic functions and Python normal variables, so if 'foo' is both a Python variable and an alias, the alias can not be executed until 'del foo' removes the Python variable. You can use the %l specifier in an alias definition to represent the whole line when the alias is called. For example:: In [2]: alias bracket echo "Input in brackets: <%l>" In [3]: bracket hello world Input in brackets: <hello world> You can also define aliases with parameters using %s specifiers (one per parameter):: In [1]: alias parts echo first %s second %s In [2]: %parts A B first A second B In [3]: %parts A Incorrect number of arguments: 2 expected. parts is an alias to: 'echo first %s second %s' Note that %l and %s are mutually exclusive. You can only use one or the other in your aliases. Aliases expand Python variables just like system calls using ! or !! do: all expressions prefixed with '$' get expanded. For details of the semantic rules, see PEP-215: https://peps.python.org/pep-0215/. This is the library used by IPython for variable expansion. If you want to access a true shell variable, an extra $ is necessary to prevent its expansion by IPython:: In [6]: alias show echo In [7]: PATH='A Python string' In [8]: show $PATH A Python string In [9]: show $$PATH /usr/local/lf9560/bin:/usr/local/intel/compiler70/ia32/bin:... You can use the alias facility to access all of $PATH. See the %rehashx function, which automatically creates aliases for the contents of your $PATH. If called with no parameters, %alias prints the current alias table for your system. For posix systems, the default aliases are 'cat', 'cp', 'mv', 'rm', 'rmdir', and 'mkdir', and other platform-specific aliases are added. For windows-based systems, the default aliases are 'copy', 'ddir', 'echo', 'ls', 'ldir', 'mkdir', 'ren', and 'rmdir'. You can see the definition of alias by adding a question mark in the end:: In [1]: cat?

Under Windows, it checks executability as a match against a '|'-separated string of extensions, stored in the IPython config variable win_exec_ext. This defaults to 'exe|com|bat'.

Change the current working directory. This command automatically maintains an internal list of directories you visit during your IPython session, in the variable ``_dh``. The command :magic:`%dhist` shows this history nicely formatted. You can also do ``cd -<tab>`` to see directory history conveniently. Usage: - ``cd 'dir'``: changes to directory 'dir'. - ``cd -``: changes to the last visited directory. - ``cd -<n>``: changes to the n-th directory in the directory history. - ``cd --foo``: change to directory that matches 'foo' in history - ``cd -b <bookmark_name>``: jump to a bookmark set by %bookmark - Hitting a tab key after ``cd -b`` allows you to tab-complete bookmark names. .. note:: ``cd <bookmark_name>`` is enough if there is no directory ``<bookmark_name>``, but a bookmark with the name exists. Options: -q Be quiet. Do not print the working directory after the cd command is executed. By default IPython's cd command does print this directory, since the default prompts do not display path information. .. note:: Note that ``!cd`` doesn't work for this purpose because the shell where ``!command`` runs is immediately discarded after executing 'command'.

DEPRECATED. Suboptimal, retained for backwards compatibility. You should use the form 'var = !command' instead. Example: "%sc -l myfiles = ls ~" should now be written as "myfiles = !ls ~" myfiles.s, myfiles.l and myfiles.n still apply as documented below. -- %sc [options] varname=command IPython will run the given command using commands.getoutput(), and will then update the user's interactive namespace with a variable called varname, containing the value of the call. Your command can contain shell wildcards, pipes, etc. The '=' sign in the syntax is mandatory, and the variable name you supply must follow Python's standard conventions for valid names. (A special format without variable name exists for internal use) Options: -l: list output. Split the output on newlines into a list before assigning it to the given variable. By default the output is stored as a single string. -v: verbose. Print the contents of the variable. In most cases you should not need to split as a list, because the returned value is a special type of string which can automatically provide its contents either as a list (split on newlines) or as a space-separated string. These are convenient, respectively, either for sequential processing or to be passed to a shell command. For example:: # Capture into variable a In [1]: sc a=ls *py # a is a string with embedded newlines In [2]: a Out[2]: 'setup.py\nwin32_manual_post_install.py' # which can be seen as a list: In [3]: a.l Out[3]: ['setup.py', 'win32_manual_post_install.py'] # or as a whitespace-separated string: In [4]: a.s Out[4]: 'setup.py win32_manual_post_install.py' # a.s is useful to pass as a single command line: In [5]: !wc -l $a.s 146 setup.py 130 win32_manual_post_install.py 276 total # while the list form is useful to loop over: In [6]: for f in a.l: ...: !wc -l $f ...: 146 setup.py 130 win32_manual_post_install.py Similarly, the lists returned by the -l option are also special, in the sense that you can equally invoke the .s attribute on them to automatically get a whitespace-separated string from their contents:: In [7]: sc -l b=ls *py In [8]: b Out[8]: ['setup.py', 'win32_manual_post_install.py'] In [9]: b.s Out[9]: 'setup.py win32_manual_post_install.py' In summary, both the lists and strings used for output capture have the following special attributes:: .l (or .list) : value as list. .n (or .nlstr): value as newline-separated string. .s (or .spstr): value as space-separated string. �lvr� r= )r r �l)rG �vz%s == %sN) r� rG r> rO r � getoutputrB r r~ �update) r, rL r� r� r� �_rM rG �outr0 r0 r1 �sc4 s ] z OSMagics.scc C s^ |du r| j �|�S | �|dd�\}}| j �|�}|�d|�d��}|rV|| j j|< n|S dS )a' Shell execute - run shell command and capture output (!! is short-hand). %sx command IPython will run the given command using commands.getoutput(), and return the result formatted as a list (split on '\n'). Since the output is _returned_, it will be stored in ipython's regular output cache Out[N] and in the '_N' automatic variables. Notes: 1) If an input line begins with '!!', then %sx is automatically invoked. That is, while:: !ls causes ipython to simply issue system('ls'), typing:: !!ls is a shorthand equivalent to:: %sx ls 2) %sx differs from %sc in that %sx automatically splits into a list, like '%sc -l'. The reason for this is to make it as easy as possible to process line-oriented shell output via further python commands. %sc is meant to provide much finer control, but requires more typing. 3) Just like %sc -l, this is a list with special attributes: :: .l (or .list) : value as list. .n (or .nlstr): value as newline-separated string. .s (or .spstr): value as whitespace-separated string. This is very useful when trying to use such lists as arguments to system commands.Nr zout=r� �o)r r� r� rQ r~ )r, �line�cellr� r� �outputZout_namer0 r0 r1 �sx� s * z OSMagics.sx�system�!c C s� | j |ddd�\}}t|�dkr(td��| jj�di �}d|v r�z |d }W n. tyz } ztd �|�W Y d }~nHd }~0 0 z ||= W n2 ty� } ztd | �|�W Y d }~n d }~0 0 n�d |v r�i }n�d |v �r.t|�}|r�t t t|��}nd}dt |� d } t d� |D ]} t | | || f � �qnN|�s>td��n>t|�dk�r^t �� ||d < n t|�dk�r||d ||d < || jjd< d S )ah Manage IPython's bookmark system. %bookmark <name> - set bookmark to current dir %bookmark <name> <dir> - set bookmark to <dir> %bookmark -l - list all bookmarks %bookmark -d <name> - remove bookmark %bookmark -r - remove all bookmarks You can later on access a bookmarked folder with:: %cd -b <name> or simply '%cd <name>' if there is no directory called <name> AND there is such a bookmark defined.

This magic is similar to the cat utility, but it will assume the file to be Python source and will show it with syntax highlighting. This magic command can either take a local filename, an url, an history range (see %history) or a macro as argument.
