Answer:
sed '/march/{d;}' birthdays.txt > result
.txt
Explanation:
sed syntax is basically:
<em>sed '/expression/{command;command;...;}' inputfile > outputfile</em>
- First, for the expression part, we use /march/ to match all lines containing that string.
- Then for the command part, we only use {d} command to delete every matching line found.
