Burberry watch serial number check. Others have said the difference is sourcing vs executing but no one has outlined the functional differences. The biggest functional difference is that exit, cd, and variable assignments will affect the currently running shell if you source it, but not if you execute it. To demonstrate, try the following: $ cat test.sh #!/bin/bash mkdir -p test cd test pwd foo=bar echo script foo: $foo $./test.sh /Users/kevin/test script foo: bar $ echo $foo $ pwd /Users/kevin $.
MyScript Stylus is set up like any other keyboard replacement app and comes packed with the usual set of essential features, such as suggestions in a bar above the input area. Though, it does has some very intuitive features that set it apart from other similar solutions. May 4, 2015 - MyScript Stylus - Handwriting Keyboard - Designed for iPhone, iPod and iPad, MyScript Stylus provides a handwriting alternative to onscreen.
Test.sh /Users/kevin/test script foo: bar $ echo $foo bar $ pwd /Users/kevin/test $ Now try this: $ cat test.sh #!/bin/bash exit $./test.sh $. Test.sh [Process completed] As you can see, exit in an executed script will finish that script, but if you source a script with exit, it will exit your current shell!
Help source says: source: source filename [arguments] Execute commands from a file in the current shell. Read and execute commands from FILENAME in the current shell. The entries in $PATH are used to find the directory containing FILENAME. If any ARGUMENTS are supplied, they become the positional parameters when FILENAME is executed. Exit Status: Returns the status of the last command executed in FILENAME; fails if FILENAME cannot be read. Source is a synonym for., that means you can write both. Myshellscript or source myshellscript What they do: source reads every line of the file (line by line) and executes it in the current shell.
But./myshellscript executes the file in the current directory if it has the rights to do so. This could also be /tmp/foo/bar/myshellscript (to execute the file myshellscript which is in the directory /tmp/foo/bar) or /usr/local/bin/myshellscript That means, that here the dot is just the current directory. Therefore./myshellscript executes the file called myshellscript in the current directory. For example try cd. Which changes to the current directory (no real change;-)) or ls.
Which lists the content of the current directory. And as @Alvin Wong commented: You can try this script #!/bin/foobarNonExisting echo 'This is the Shell that executes me:' echo $SHELL with.
Or source to see, that it does not read the shebang. It just uses your current shell. Executing the script itself would lead to an error. Is a synonym to the source command. Instead of forking a sub shell to execute the script it reads the script into the current shell environment. In other words./script will execute the script in a spawned sub shell and does the processing there.
Script reads the script into your current shell where your current shell will process the commands. They do the similar things. Script you are reading and./script you are executing (by spawning a sub shell) so the appropriate permissions are required to do either. There are many answers explaining that.
