Selecting lines with sed
Hi all,
I have a file with special characters like this

file1
Code:
691775025 ýÄqJ8^Z^Y{ 2004-08-23E P 100.00
45585025 0527541139295037342008-07-25OEP 100.00
6983025 ýB<9D>x<^F^Xb 2004-11-16SPP 100.00

I need a sed command to print the lines which don't have special characters.ie., only line 2 should be printed from the file1

I was trying with the following command and it wasn't working.

Code:
sed -e '/^[-.0-9A-Za-z\s]$/p' file1

Can anybody help on this.

I'll try to explain it (in english).

the -v options shows lines that doesn't match the expresion.

"\^" is the expresion, I have considered the ^ character as the only "special" character in your expresions...

Maybe the solution doesn't run for other lines...

All right, now I got it. Shame on me that I did not find out that myself. I was staring at that code and was wondering how can be that it filters out all the mentioned special chars Smilie

Hi,
In my case, anything other than the following should be considered as special char.

Alphanumeric
-
.
whitespace(can be anywhere in the line)
