I have created a address book file. Insertion of Record (using >> symbol)and searching of record (using grep command) into the address book is also working correctly. Now I want to delete a record into a file. Any body can help me in this case without using sed and awk18 18.
Thanks and best regards,

sed "/pattern/d" file > tmp
mv tmp file

awk ' $0 !~ /pattern/ { print > "file" } < file

perl -i -ne ' print if( $_ !~ /pattern/ ) ' file

joining this to the list,

sed -n '/pattern/!p' filename

That will only work for files with size lesser than the amount
of bytes your awk utility reads from files at a time.

Yet to verify that!

and this!

awk '{ if( !match($0, "pattern") ) { print } }' file

Sorry for the statement, i had to write without sed and awk. Please tell me the solution without sed and awk
