Line Wrapping using Sed
Hi,

I want to wrap the lines if a line starts with number. I tried the following sed command, but I do not get the required output. It is replacing the first number.

Can some one please help me on this?

Command I used
Code:
sed -e :a -e '$!N;s/\n[0-9]//;ta'  -e 'P;D' testfile

I/P file:
Code:
Test_sed,
05/20/2010,15:06,05/20/2010,15:06,SU,91107794/1,

O/P I got:
Code:
Test_sed,5/20/2010,15:06,05/20/2010,15:06,SU,91107794/1,

Expected output
Code:
Test_sed,05/20/2010,15:06,05/20/2010,15:06,SU,91107794/1,

Hi,

not tested but you could try
Code:
sed -e :a -e  '$!N;s/\n\([0-9]\)/\1/;ta'  -e 'P;D' testfile
