The script cadenv is used to set environment variables? Run the cadenv script in the current shell (source):

Code:
. ./cadenv <env>

Suppose we want to sort a huge collection of 1 trillion, 10^12, elements. Doing so with Selection Sort or Insertion Sort would require about n^2 = (10^12)^2 = 10^24 or 1 sextillion comparisons.
True or False?

source(n)						       Tcl Built-In Commands							 source(n)

__________________________________________________________________________________________________________________________________________________

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 restriction 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 "32" or "u001a", which will be safely substituted by the Tcl interpreter into "^Z". 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 } SEE ALSO
file(n), cd(n), encoding(n), info(n) KEYWORDS
file, script Tcl source(n)
