uppercase

[Andrej Vavro]

One more syntax question:
I need to switch a text to uppercase in bash script.

VARIABLE='abcd'

I need to work with 'ABCD'


Regards,
Andrej

Hi, Andrej

VARIABLE=`echo $VARIABLE | tr [a-z] [A-Z]`

Best Regards.
Frank.

Hi, Andrej,
Be careful with the quotation, copy and paste because they aren't normal quotes. This quotes doing an execution and the result is returned to the shell.

hi

tr is the right command, but I just wanter to add that using classes is somtime more efficient :

echo $VAR | tr '[:lower:]' '[:upper:]'

There a a lot of classes ...

I had to do this except go to lowercase... but below is what you want

variable=$(cat file | awk '{print toupper($1)}')
echo $variable
