put variable in for loop pls ... 1

[h3nd]

Hi guys,

Here's part of my code

...
parameter="Current_Rates"

for f in `find . -name "*.csv" -maxdepth 1`
        do
        dir=`echo $f | sed 's/.*\(.\{8\}\).csv$/\1/'`
                if [[ $dir -lt $tdate ]];then
                                echo $parameter_$dir
                fi
        done

why the variable $parameter can not include in for loop ?
how do I put the variable $parameter into my for loop ?

Thanks guys,

Try this...

...
parameter="Current_Rates"

for f in `find . -name "*.csv" -maxdepth 1`
        do
        dir=`echo $f | sed 's/.*\(.\{8\}\).csv$/\1/'`
                if [[ $dir -lt $tdate ]];then
                                echo $[b]{[/b]parameter[b]}[/b]_$dir
                fi
        done

Add curly braces around the variable name.

Thx, it's working.

The reason, the shell thought the underscore was part of the variable name and the variable "[tt]parameter_[/tt]" doesn't exist. The curly braces tell it exactly what the variable name is.
