Answer / dhanooj
1)open file ,point to that perticular line, give
command "dd"
it will delete the line and save the file by pressing ":wq"
2)grep -v 'string pattern' file > newfile
it will create newfile with all lines from the file
except the lines containing "string pattern"
3)sed "pattern/d" filename >tmpfile
will delete all lines having this pattern and will write
to newfile
4)sed "3,d" filename >tmpfile
will remove the line 3 and will write to tmpfile
