comment Help with Find function in Linux
The command seems correct. Are you sure there exists such a file? The only discrepancy between your text and your command is that the command has -readable while you don't mention in your text that the file has to be readable.

comment Possible mcrypt spelling error?
It's never a surprise to find something as lame and careless as a spelling error in anything to do with PHP.. (Sorry, couldn't help myself.)

comment Are [ “$VAR” = “” ] and [ -z “$VAR” ] always equivalent?
Thanks for the clarification, @Gilles. While I don't know whether or not I have ever personally programmed with a shell that was antique enough to trigger that problem, I learned the habit from a mentor who surely did.

comment Create an Excel/.csv file with Times New Roman Font, programmatically?
Are you using a library to generate "execl/.csv" files? If so, you need to say which one and which programming language. By the way, a text/csv file does not include any metadata about fonts. Also, assuming you are using a programming language and a library that helps you generate these files, this is a programming question and belongs on Stack Overglow.

comment Are [ “$VAR” = “” ] and [ -z “$VAR” ] always equivalent?
I though for sure that [ "$VAR" = "" ] was wrong because if the contents of $VAR were to start with a hyphen then it would lead to a syntax error, for example if $VAR contains -z then it would expand to [ -z = "" ] — would that test if = is empty (which it isn't) and then treat "" as an extraneous argument? But I cannot seem to make it fail that way now that I try it after reading your answer! I've been using contructs like [ "x$VAR" = "xfoo" ] to guard against special characters in $VAR for decades, perhaps unnecessarily!

comment how to make special program run with different version of java from system?
Yes, it sounds like using a shell script and $JAVA_HOME could work. What have you tried?

comment How to avoid recursive directory traversal for syncing two directories?
@richard, what I meant to say is that if anyone has some great idea to improve the situation, perhaps an improvement to POSIX that's compelling enough to get adapted by several kernels, perhaps something nobody has though of before, that's fantastic, but it wouldn't be a question.

comment Shell namespaces
Thanks for the clarification. I expect that the answer is negative. The usual shell programming paradigm is that when you want to isolate changes, you do it in a subshell, which creating one is just about the ( easiest thing ever ). But that's not quite what you're after. I guess you could do ( stuff in subshell; exec env ) | sed 's/^/namespace_/' and eval the result in the parent shell but that's kind of nasty.
