Remove particular record from a file

HiSmilie,
I am having 110 records in a file and I want to delete particular record (say 63rd) . Which command can be use to achieve this ?

in ksh you could have a script with: -

Code:
LINE=63

nawk -v ln=$LINE ' NR != ln { print } ' infile


or on the command line: -

Code:
nawk ' NR != 63 { print } ' infile

or to redirect to a file: -

Code:
nawk ' NR != 63 { print } ' infile > outfile

Hi,

Code:
sed -n '63!p' file

Code:
sed '63d' infile > outfile

or
Code:
sed -i '63d' inoutfile

The records need to be newline separated, and record 1 needs to be on line 1
