Hi,
Can you please help me with this one: I write an "if" statement, something like this:
if[size -ge 700]
then
echo "big file"

"if" <space> <expression>
then
<command>
<command>
"fi"
The <expression> in your case is:
"[" <space> "$size" <space> "-ge" <space> "700" <space> "]"

-lt, less than
-le, less than or equal to
-gt, greater than
-ge, greater than or equal to
-ne, not equal to

=, equal
!=, not equal to

It saves me lot of typing and space/lines when I do not use full 'if' keyword and construct, instead use ..
&& <statement> || <statement>
that perfectly replaces..
if ; then
<statement>
else
<statement>
fi
