Re: Make variables uppercase in bash.
I suppose you can't use tr?
echo ${var:2:1} | tr 'a-z' 'A-Z'
would work, but I take it you want to avoid using tr?

| I think I may need to be a little more specific. We are writing a bash script that reads some stuff and builds a control file for Oracle's sqlldr, and then we execute sqlldr with the build control file. Our code looks much like this:
The myAmicFiles just looks like this:
amici.990120
amici.990220
amico.990520
amico.990620
I need the i or o to be uppercase.

So in this line:
quote:
echo " column3 CONSTANT '" ${LINE:4:1} | tr 'a-z' 'A-Z' "'," >> file_loader.ctl
You want just the capital letter?
E.g. for LINE = amico.990120 you want just the O?
Or do you want amicO.990120 ?

Probably the easiest thing to do would be to set a variable for the letter first, then just use that variable.
e.g instead of:
bash code:echo " column3 CONSTANT '" ${LINE:4:1} | tr 'a-z' 'A-Z' "'," >> file_loader.ctl
try:
bash code:the_char=`echo ${LINE:4:1} | tr a-z A-Z`
echo " column3 CONSTANT '$the_char'," >> file_loader.tcl
Again, assuming you just want the O there and not the full name. If you want the full name, it'd be slightly more involved but not terribly so.

The above line just returns the given string literal, not the results of the echo. |
