Shell Programming and Scripting

Hi

Im running this command on AIX in ksh.
My input file samp1 contains
1
2
123
12345

When I execute the following sed i dont get a matching pattern
sed -n '/[0-9]{1}/p' samp1

Can anyone help me with this simple thing

Try escaping the curly braces.

thanks it worked..

But similarly
sed -n '/[0-9]\+/p' samp1
or
sed -n '/[0-9]+/p' samp1
did not give any results
