SED line delete - string at certain position help

[AlStl]

Hi,

I would like to remove all the lines in a file that contains letters (upper case) KJ at postions 6-7 from the begging on line.

an example would be:

1ABNPKJLDS9PORT_SIL 200708800 copu
1PORPKJLDUS9PORT_UYT 200700000 KLPU
1ABTPKJLDS9JOB_SIL 200708800 CPOI
1POIPKJLDUS9PO_UYT 200700000 YUTO
1ABTPTXLDS9JOB_SIL 200708800 CPOI
1POIPTXLDUS9PO_UYT 200700000 YUTO
1POIPMILDUS9PO_UYT 200700000 YUTO

Resulting file should only have:

1ABTPTXLDS9JOB_SIL 200708800 CPOI
1POIPTXLDUS9PO_UYT 200700000 YUTO
1POIPMILDUS9PO_UYT 200700000 YUTO

I am trying this, but its not working:

sed -i '/^.....KJ/d' file_name


Any help will be appreciated.

My system (Solaris) chokes on the '-i', but other than that it's working as expected.

What results or errors are you getting?

sed -i '/^.{5}KJ/d' file

Works for me

Could you possibly have a control character, or other non-printing character that you can't see in there? Try this...

# Just chop off first five characters to see if your 'KJ's start with 'KJ'
sed '/^.....//g' file

# Look for non-displaying characters
od -c file

# Don't use sed
grep -v '^.....KJ' file
