add , to variable

[Marcel1958]

I have the variable $TRY.

When i print this variable the result is:

1242

Now i will add an , between 124 an the last 2

How can i add this so the result will be

124,2

assuming your counter '2' is another variable ${counter}

echo "${TRY},${counter}"

No it is the same.

I see what you mean NOW.
What shell are you using?

Korne shell.

It is the result of:

TRY=$TOTAL01/$COUNT01

In $TOTAL01 and $COUNT01 i removed the , with
tr -d &quot;,&quot;

here's the sed way

echo &quot;${TRY}&quot; | sed -e 's:\(.*\)\(.\):\1,\2:'

Thanks Vlad for the support.

Can you tell me the function of the given command. Man sed don't tell me the exact working of the parameters you gave.

sed -e 's:\(.*\)\(.\):\1,\2:'

\(.*\)\ - capture all the chars from the beginning in capture '1'

(.\) - capture the trailing char in capture '2'

\1,\2 - ouput capture '1' followed by a ',' followed by capture '2'
