source(1t) Tcl Built-In Commands source(1t) ______________________________________________________________________________ NAME source - Evaluate a file or resource as a Tcl script SYNOPSIS source fileName source -encoding encodingName fileName ______________________________________________________________________________ DESCRIPTION This command takes the contents of the specified file or resource and passes it to the Tcl interpreter as a text script. The return value from source is the return value of the last command executed in the script. If an error occurs in evaluating the contents of the script then the source command will return that error. If a return command is invoked from within the script then the remainder of the file will be skipped and the source command will return normally with the result from the return command. The end-of-file character for files is "\32" (^Z) for all platforms. The source command will read files up to this character. This restric- tion does not exist for the read or gets commands, allowing for files containing code and data segments (scripted documents). If you require a "^Z" in code for string comparison, you can use "\032" or "\u001a", which will be safely substituted by the Tcl interpreter into "^Z". A leading BOM (Byte order mark) contained in the file is ignored for unicode encodings (utf-8, unicode). The -encoding option is used to specify the encoding of the data stored in fileName. When the -encoding option is omitted, the system encoding is assumed. EXAMPLE Run the script in the file foo.tcl and then the script in the file bar.tcl: source foo.tcl source bar.tcl Alternatively: foreach scriptFile {foo.tcl bar.tcl} { source $scriptFile } ATTRIBUTES See attributes(7) for descriptions of the following attributes: +---------------+------------------+ |ATTRIBUTE TYPE | ATTRIBUTE VALUE | +---------------+------------------+ |Availability | runtime/tcl-8 | +---------------+------------------+ |Stability | Uncommitted | +---------------+------------------+ SEE ALSO file(n), cd(n), encoding(n), info(n) KEYWORDS file, script NOTES Source code for open source software components in Oracle Solaris can be found at https://www.oracle.com/downloads/opensource/solaris-source- code-downloads.html.
