Typeset conversion problem from ksh to bash
Hi,

Code:
typeset -l sgf  # all lowercase letters
typeset -u SGF  # all uppercase letters
sgf=$1
SGF=$sgf

these lines used in my scripts . It ran fine in ksh but when we convert this to bash it erroring out.

I like to know what the use of typeset ??

Hi,

In bash we can use decare instead of typeset but its options is limited.
Code:
declare: usage: declare [-afFirtx] [-p] [name[=value] ...]

I used functions , its worked fine
Code:
toUpper() { echo $1 | tr "[:lower:]" "[:upper:]" } GENDER=male GENDER=`toUpper $GENDER` echo $GENDER
toLower() { echo $1 | tr "[:upper:]" "[:lower:]" } GENDER=MALE GENDER=`toLower $GENDER` echo $GENDER

Thnks,
kanagaraj

Hi.

Two data points: typeset -l and typeset -u seem to work correctly in:
Code:
GNU bash 4.0.35

but not in:
Code:
GNU bash 3.2.39

cheers, drl
