Use strict.

velocitymodel has asked for the wisdom of the Perl Monks concerning the following question:

Dear monks,

I am writing a code and keep coming up with errors for certain commands.

#!/usr/bin/perl
$use strict;
strict command not found
[download]

 #!/usr/bin/perl
use strict;
No command 'use' found, did you mean ....
[download]

I get the same error message when using 'my' also. How do I correct this?

You are not using `perl` to execute your scripts. Sounds like you are using a shell. Those messages are not coming from Perl. For a missing module, Perl would have used `Can't locate strict.pm in @INC (@INC contains: ...) at ....` [download] Note that you have a space before "#!" in the second snippet, but they must be the first characters of the file to have their special meaning. Once you start running your snippets with Perl, you'll still have a problem with the first snippet. `Bareword found where operator expected at ..., near "$use strict" (Missing operator before strict?) syntax error at ..., near "$use strict" Execution of -e aborted due to compilation errors.` [download] Get rid of the "$".

In your first example, Perl sees `$use` as a variable, and `strict` as a command (or 'verb') so what you've written won't work. But your second example appears reasonable... so you may need to check your installation -- are your modules where they should be; if you built your local Perl, did you do so properly? PS: it's good that you're using `strict`; go the whole way now, and add `use warnings` to see the helpful messages it will provide (or see the same errors with respect to `warnings.pm`. As to use of `my`, I have no clue what you mean: `my $use strict`; `my strict`; my what?.	[reply] [d/l] [select]

The first error message is a typical shell error. If you execute the first snippet in a shell, it will disregard the first line (it's a comment), disregard the $use (it's undefined, hence an empty string), and cannot find the command 'strict'. I do not know which program has errors of the form "No command 'use' found, did you mean ...", but I do know Perl doesn't have errors looking like that.	[reply]

I do not know which program has errors of the form "No command 'use' found, did you mean ..." It's what ubuntu does when it thinks you're trying to run a command from a package you have not installed: `$ hgh No command 'hgh' found, did you mean: Command 'huh' from package 'orville-write' (universe) Command 'hg' from package 'mercurial' (universe) hgh: command not found` [download]	[reply] [d/l]
