4/29/2023 0 Comments Run unix commands in ruby runnerThe former is by far the simplest, the latter is a property list with environment variables read by Finder when you login, so values set here should affect all applications. Either via Preferences → Advanced → Shell Variables or by editing ~/.MacOSX/ist. There are two ways to setup PATH for TextMate. TextMate inherits the value of PATH from Finder, which has only a few search locations specified, so for many users, it is necessary to augment this PATH if they need TextMate to find git, pdflatex, or similar commands not included with Mac OS X. For example ruby is located in /usr/bin/ruby and svn is (for me) located in /opt/local/bin/svn. When running a command from Terminal, the shell will use the value of the PATH variable to locate it (when it is specified without an absolute location). You can also set that documents should be saved before executing the command and give the command a key equivalent or tab trigger. for commands which build the project and show results, incrementally). for commands which lookup help for the current word) or HTML (e.g. you can set what to do with input/output, even have the output shown as a tool tip (e.g. ![]() The options here are the same as those of option 2, i.e. The first two options are mostly for one-shot commands, whereas commands created in the Bundle Editor are for stuff you want to run again later. In the current document, either press ⌃R with no selection to run the current line as a shell command, or select one or more lines and use ⌃R to run the selection as a shell script (it supports shebang as well).įrom the Text menu you can select Filter Through Command… (⌥⌘R) which opens a panel where you can enter a shell command to run and set what should be given as input (stdin) plus what to do with the output of the command (often you want to set input to the selected text and let the output replace the selection).Ĭommands via the Bundle Editor. TextMate allows shell commands to be executed in different contexts. on Unix-like systems, same as ENVRUBYSHELL (or ENVCOMSPEC on Windows NT. as done when launching Terminal and entering commands to execute.įor a thorough introduction to the shell scripting language have a look at this shell tutorial provided by Apple. Replaces the current process by running the given external command. cat( "/etc/printcap") | sh.The shell is a scripting language used to piece together various programs (shell commands), and often in an interactive way, e.g. ![]() Output it to a new file relative to the pwd of etc/printcap, generated by cupsd, and then In this example we will read the operating system file close end print pwd end end end Pipe /etc/printcap into a file ¶ ↑ Mkdir dir cd( dir) do f = open( "tmpFile", "w")į. transact do mkdir "shell-test-1" unless exists?( "shell-test-1") Sh.cd to cd, because the scope within the block This example is identical to the first, except we're using Shell::CommandProcessor#transact.Įxecutes the given block against self, in this case sh our Shell object. pwd # output the process working directory end end Temp file creation with self ¶ ↑ close # close the file handler end print sh. open( "tmpFile", "w") # open a new file in write mode f. cd( dir) do # change to the `dir` directory f = sh. mkdir dir # make dir if it doesn't already exist sh. For Example: exec ('echo p Product.first b Billing.firstrails c') When I tried something similar to the example, it would always try to execute the two commands before launching console. cd( "shell-test-1") # Change to the /tmp/shell-test-1 directory for dir in I am currently trying to figure out if it is possible to run multiple commends within one line on a rails console through Unix shell or within a ruby script. ![]() # make the 'shell-test-1' directory if it doesn't already exist sh. cd( "/tmp") # Change to the /tmp directory sh. In this example we will create three tmpFile's in threeĭifferent folders under the /tmp directory. Like sh/ csh by using native facilities of Ruby. It provides users the ability to execute commands with filters and pipes, Shell implements an idiomatic Ruby interface for
