We use a UNIX-based system (Lawson) at work and I was given this command to request a data extract from the db admin. The only thing I really understand is the last line as it appears to be joining the files created from the first three lines into one. Is there anyone who can help me breakdown the rest of the code. I assume "find" means exactly what it states and I think "grep" is extracting whatever is found. But what about the rest of the syntax in red, green and blue. And what does "/tmp" mean?
Trying to install something. Can someone explain what this means?
chmod -R a+r .
chmod -R a+w logo.gif tempdir/ templates_c/
I recognize that file permissions are being changed (chmod), but beyond that, it's Greek to me. (6 Replies)

source
source(n) Tcl Built-In Commands source(n)
__________________________________________________________________________________________________________________________________________________NAME
source - Evaluate a file or resource as a Tcl script
SYNOPSIS
source fileName
source -rsrc resourceName ?fileName?
source -rsrcid resourceId ?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 inter- |
preter into ``^Z''.
The -rsrc and -rsrcid forms of this command are only available on Macintosh computers. These versions of the command allow you to source a
script from a TEXT resource. You may specify what TEXT resource to source by either name or id. By default Tcl searches all open resource
files, which include the current application and any loaded C extensions. Alternatively, you may specify the fileName where the TEXT
resource can be found.
