Method Detail

installExecutable
```
public static java.lang.String installExecutable(java.util.Map<?,?> flags,
                                 java.lang.String executable)
```
Returns a string for checking whether the given executable is available, and installing it if necessary.
Uses installPackage(java.lang.String) and accepts the same flags e.g. for apt, yum, rpm.

installExecutable

public static java.lang.String installExecutable(java.lang.String executable)

quiet

public static java.lang.String quiet(java.lang.String command)

Returns a command with all output redirected to /dev/null

ok

public static java.lang.String ok(java.lang.String command)

Returns a command that always exits successfully

sudo
```
public static java.lang.String sudo(java.lang.String command)
```
Returns a command for safely running as root, using sudo.
Ensuring non-blocking if password not set by using -n which means to exit if password required (this is unsupported in Ubuntu 8 but all modern OS's seem okay with this!), and (perhaps unnecessarily ?) -S which reads from stdin (routed to /dev/null, it was claimed here previously, though I'm not sure?).
Also specify -E to pass the parent environment in.
If already root, simply runs the command, wrapped in brackets in case it is backgrounded.
The command is not quoted or escaped in any ways. If you are doing privileged redirect you may need to pass e.g. "bash -c 'echo hi > file'".
If null is supplied, it is returned (sometimes used to indicate no command desired).

sudoAsUser
```
@Beta
public static java.lang.String sudoAsUser(java.lang.String user,
                               java.lang.String command)
```
Deprecated. since 0.7.0 semantics of this are fiddly, e.g. whether user gets their environment

sudo to a given user and run the indicated command;

addSbinPathCommand

public static java.lang.String addSbinPathCommand()

executeCommandThenAsUserTeeOutputToFile

public static java.lang.String executeCommandThenAsUserTeeOutputToFile(java.lang.String commandWhoseOutputToWrite,
                                                       java.lang.String user,
                                                       java.lang.String file)

executes a command, then as user tees the output to the given file. useful e.g. for appending to a file which is only writable by root or a priveleged user.

dontRequireTtyForSudo
```
public static java.lang.String dontRequireTtyForSudo()
```
some machines require a tty for sudo; brooklyn by default does not use a tty (so that it can get separate error+stdout streams); you can enable a tty as an option to every ssh command, or you can do it once and modify the machine so that a tty is not subsequently required.
this command must be run with allocatePTY set as a flag to ssh. see SshTasks.dontRequireTtyForSudo which sets that up.
(having a tty for sudo seems like another case of imaginary security which is just irritating. like water restrictions at airport security.)

generateKeyInDotSshIdRsaIfNotThere
```
public static java.lang.String generateKeyInDotSshIdRsaIfNotThere()
```
generates ~/.ssh/id_rsa if that file does not exist

ifFileExistsElse0
```
public static java.lang.String ifFileExistsElse0(java.lang.String path,
                                 java.lang.String command)
```
Returns a command that runs only if the specified file (or link or directory) exists; if the command runs and fails that exit is preserved (but if the file does not exist exit code is zero). Executed as { { not-file-exists && ok ; } || command ; } for portability. ("if [ ... ] ; then xxx ; else xxx ; fi" syntax is not quite as portable, I seem to recall (not sure, Alex Aug 2013).)

ifFileExistsElse1
```
public static java.lang.String ifFileExistsElse1(java.lang.String path,
                                 java.lang.String command)
```
as ifFileExistsElse0(String, String) but returns non-zero if the test fails (also returns non-zero if the command fails, so you can't tell the difference :( -- we need if ; then ; else ; fi semantics for that I think, but not sure how portable that is)

ifExecutableElse0
```
public static java.lang.String ifExecutableElse0(java.lang.String executable,
                                 java.lang.String command)
```
Returns a command that runs only if the specified executable exists on the path (using `which`). if the command runs and fails that exit is preserved (but if the executable is not on the path exit code is zero).

See Also:
for implementation discussion, using { { test -z `which executable` && true ; } || command ; }







ifExecutableElse1
public static java.lang.String ifExecutableElse1(java.lang.String executable,
                                 java.lang.String command)
as ifExecutableElse0(String, String) but returns 1 if the test fails (also returns non-zero if the command fails)







ifNotExecutable
public static java.lang.String ifNotExecutable(java.lang.String command,
                               java.lang.String statement)
Returns a command which
 executes statement only if command is NOT found in $PATH

command - 
statement - 
Returns:
command

Returns a command that runs only if the specified executable exists on the path (using `which`).
 if the command runs and fails that exit is preserved (but if the executable is not on the path exit code is zero).
See Also:
for implementation discussion, using { { test -z `which executable` && true ; } || command ; }

                                                                         java.util.List<java.lang.String> otherwise)







chain
public static java.lang.String chain(java.util.Collection<java.lang.String> commands)
Returns a sequence of chained commands that runs until one of them fails (i.e. joined by '&&')
 This currently runs as a subshell (so exits are swallowed) but behaviour may be changed imminently. 
 (Use chainGroup(Collection) or chainSubshell(Collection) to be clear.)

Returns a command for installing the given package.
 
 Warns, but does not fail or return non-zero if it ultimately fails.
 

 Flags can contain common overrides for apt, yum, port and brew
 as the package names can be different for each of those. Setting the default package name to
 null will use only the overridden package manager values. The onlyifmissing flag
 adds a check for an executable, and only attempts to install packages if it is not found.
 
 installPackage(ImmutableMap.of("yum", "openssl-devel", "apt", "openssl libssl-dev zlib1g-dev"), "libssl-devel");
 installPackage(ImmutableMap.of("apt", "libaio1"), null);
