Shell Programming and Scripting

[/COLOR]ya i have tried that.. still it is not working..
The ascii value is \032 . It will be seen as ^Z character in VI.

Ashiwn..did you try the second method suggested by bartus11? it should be working.

Guru.

Hey.. I tried that..
This is the result.It is printing the record with the junk characters as well.

$ awk '/[^a-zA-Z|#$%]/' junk1.txt
15|Susan|123
john|zint^Z|123

^Z is not printable character, so it can't be output by AWK. Maybe there are just two normal characters: "^" and "Z"? Try

Code:

cat junk1.txt

and see if "^Z" apears there. If it does, then it is not CTRL+Z, just regular "^" and "Z". Also you can post output of

Code:

xxd junk1.txt

so we can see exactly how does your test data look like.

Odd. It should match [:cntrl:].

Code:

$ printf '\032' | awk '/[[:cntrl:]]/ {print "MATCHED SUCCESSFULLY"}'
MATCHED SUCCESSFULLY

A posix-compliant sed alternative which only needs to read the file once:

Code:

sed -n '/^[^[:cntrl:]]*$/{p;d;}; w junk' data > nojunk

Hi,

This is the output i get if i try xxd and "od -c ". If u see there is a special character after ziet ( 032) in the first record. Second record is good one.

$ od -c junk1.txt
0000000 2 0 6 1 | j o h n | z i e t 032 |
0000020 7 \n 1 2 3 4 | a s b c | b c f g
0000040 | 1 0 \n
0000044

$ xxd junk1.txt
0000000: 3230 3631 7c6a 6f68 6e7c 7a69 6574 1a7c 2061|john|ziet.|
0000010: 370a 3132 3334 7c61 7362 637c 6263 6667 7.1234|asbc|bcfg
0000020: 7c31 300a |10.

You rewrote the code wrong... it is not

Code:

awk '/[^a-zA-Z|#$%]/' junk1.txt

but

Code:

awk '!/[^a-zA-Z|#$%]/' junk1.txt
