you can like this:


echo "string"| dd conv=ucase

Hi,

Use tr. From man tr:

Translate all lower case characters in file1 to upper case and write the result to standard output.
tr "[:lower:]" "[:upper:]"
Or: echo string | tr "[:lower:]" "[:upper:]"

Another way could be the following:

echo "string"| tr "[:lower:]" "[:upper:]"

[Dave Peeke]

typeset -u string
string="test"
echo $string
TEST

[harry d brown jr]

echo this is a test | tr "[a-z]" "[A-Z]"

Hi,

The answers are quite satisfactory but what if I wann to retain the file extensions as it is...I mean for "abc.sql", it should be "ABC.sql" convention.

Thanks

Hi Deepak,

If you only have a "single" dot, then

echo abc.def | awk -F. '{print toupper($1)"."$2}'
ABC.def

should be OK.

Rgds, Robin.

you would do something like this

NAME=`echo $STRING | awk -F. '{print $1}'
EXT=`echo $STRING | awk -F. '{print $2}'

If you want to limit your translation to files with only 1 dot in them:

for i in `ls *\.*`
do
cnt=`echo $i | awk -F. '{print NF}'`
if [ ${cnt} -eq 2 ]
then
echo $i | awk -F. '{print toupper($1)"."$2}'
fi
done

A refinement to my last post:

for i in `ls *\.*`
do
echo $i | awk -F. '{if (NF == 2) print toupper($1)"."$2}'
done

Since I did not see the sed version

sed filename 'y/abc...xyz/ABC...xyz/'

fill in the ... part with then entire alphabet. Of course this is not the pretty way to do things, but it is the sed way.

Enjoy,

i'd do like the following:

ls -1 abc.sql | awk -F "." '{system("mv" ""$0 "" toupper($1) ".sql" }'

[federico_3]

i'd do like the following:

ls -1 abc.sql | awk -F "." '{system("mv" " " $0 " " toupper($1) ".sql" }'
