shell command :h3
[Syntax:]
shell style args :pre
style = {cd} or {mkdir} or {mv} or {rm} or {rmdir} :ulb,l
{cd} arg = dir
dir = directory to change to
{mkdir} args = dir1 dir2 ...
dir1,dir2 = one or more directories to create
{mv} args = old new
old = old filename
new = new filename
{rm} args = file1 file2 ...
file1,file2 = one or more filenames to delete
{rmdir} args = dir1 dir2 ...
dir1,dir2 = one or more directories to delete :pre
:ule
[Examples:]
shell cd sub1
shell cd ..
shell mkdir tmp1 tmp2 tmp3
shell rmdir tmp1
shell mv log.lammps hold/log.1
shell rm TMP/file1 TMP/file2 :pre
[Description:]
Execute a shell command. Only a few simple file-based shell commands
are supported, in Unix-style syntax. With the exception of {cd}, all
commands are executed by only a single processor, so that
files/directories are not being manipulated by multiple processors.
The {cd} style executes the Unix "cd" command to change the working
directory. All subsequent LAMMPS commands that read/write files will
use the new directory. All processors execute this command.
The {mkdir} style executes the Unix "mkdir" command to create
one or more directories.
The {mv} style executes the Unix "mv" command to rename a file and/or
move it to a new directory.
The {rm} style executes the Unix "rm" command to remove one or more
files.
The {rmdir} style executes the Unix "rmdir" command to remove one or
more directories. A directory must be empty to be successfully
removed.
[Restrictions:]
LAMMPS does not detect errors or print warnings when any of these Unix
commands execute. E.g. if the specified directory does not exist,
executing the {cd} command will silently not do anything.
[Related commands:] none
[Default:] none
