Sed Question

hpuxrox — Thu, 03 Apr 2008 17:55:07 GMT

I have the following file,

Abc123
Abc1234
000\Abc1235
101\Abc1236
X01\Abc1237

I want to strip out anything that is before the "\" so the output would be,

Abc123
Abc1234
Abc1235
Abc1236
Abc1237

Thanks

Hello,

Say,m your lines are saved in file ZZZ.Then simply run:

# sed -e 's/^.*\\//g' ZZZ

The result is:

Abc123
Abc1234
Abc1235
Abc1236
Abc1237

Cheers,

If there are multiple "\" on the line, the I suspect you still just want the last chunk right. That's what the above will do.

And alternative using awk: awk -F\\ '{print $NF}' ZZZ

And if only data up to the first \ needs to be stripped (unlikely):

sed -e 's/^[^\\]*\\//g' x

I assumed you could just remove the "g" but that doesn't work. It seems in your and Dusan's answer, that "g" isn't needed.

The 'g' is ofcourse not needed.
Sorry. I just cut & paste Dusan first to make sure that worked, then modified.
