echo '1234567890' | sed 's/^\(.\)\(..\)\(.*\)/\1\3\2/'

echo '1234567890' | sed 's/^\(.\)\(..\)\(.*\)/\1\3\2/'
        

sed 's/^\([0-9]\)\([0-9]\{2\}\)\([0-9]*\)$/\1\3\2/' file

sed 's/^\([0-9]\)\([0-9]\{2\}\)\([0-9]*\)$/\1\3\2/' file
        

Thanks all,

can you please let me know how it is done there . I have done the same by replacing the number it is not working.

echo '1234567890' | sed 's/^\(..\)\(..\)\(.*\)/\1\3\2/'

it is working but the same below is not working

echo '1234567890' | sed 's/^\(..\)\(..\)\(.*\)/\1\3\3/'

why it is not working ??.

Thanks in advance ,
Arunkumar

It is giving you the right result albeit it may not be the result you want

$ echo '1234567890' | sed 's/^\(..\)\(..\)\(.*\)/\1\3\3/' 12567890567890

$ echo '1234567890' | sed 's/^\(..\)\(..\)\(.*\)/\1\3\3/'
12567890567890
        

thanks ... I got into my head how it works
