What did I do to screw up my CMD shell? Windows XP Pro, open a cmd window and do:
C:\>set tt = name C:\>set tt tt = name C:\>echo %tt% %tt% C:\>echo %time% 14:13:28.67
The echo command doesn't work for some reason. I can echo the built-in ...

Have you tried setting the variable with no space between .
This:
echo %tt %

But an echo of a big string is hard to read....
The performance difference is marginal, even if a large echo is faster.
Example:
echo << makes sense to you.
Check it out please.
PHP solves this problem by what is known as heredocs .

So I have a script that I debug with a bunch of echo statements. This is run every 3 minutes on my server by cron, and I sometimes leave the echo statements in there. They're not going to a browser, they're just going... anywhere?
This is a vague question...

Is that if you leave some echo statements in a PHP script and set it as a cron job, then you will start.

I often find this in scripts (and, I have to admit, write it myself):
a=`echo $x | sed "s/foo/bar/"`
or
if echo $x | grep foo then ... fi
Consider "foo" to include some regex stuff.
I feel that there should be - and most likely is - a better way to phrase...

Well, I seriously doubt you've found a bug in the echo command, so the problem is with your program.

I could replicate the problem with various shells under FreeBSD, GNU/Linux, and Solaris. It had me head-scratching for more than an hour, so I decided to post the question here.

Alternative:
echo foo | (read a ; echo $a)
Edit:
If you need $a outside the subshell, you....
echo foo | while read a; do echo $a; done
will do what you expect it to.
Due to the piping the read is executed in its own subshell .

Answer Snippets (Read the full thread at stackoverflow):
Try using the real program
/bin/echo --version
For a help section of the builtin echo, try
help echo
And for its manpage, try
man bash
If you are using the bash as your shell....
You are probably hitting the shell builtin echo .

The readPassword() method of the Console class has echoing disabled.

Answer Snippets (Read the full thread at stackoverflow):

This way you can ask for a password on the commandline but nobody can read by eavesdropping on your computer screen .
As you would normally do.
That means you can't see the characters while you are typing in the console .

This would append the OS specific newline values with echo like this:

If you are looking method and replace all echo statements with echo PHP_EOL, .
It cannot be redefined.
echo is not a function, but a language statement.
