我有一个功课，我无法弄清楚我错过了什么。我开始时只显示部门编号100.它显示部门编号100，但也显示每个行显示命令未找到。
这是我的代码：
awk '/:100:/ { print }' employees
The records in this file have 5 fields separated by colons (:). The fields are ssn, department, lastname, firstname and years_employed. Use the employees file to create output where the employees are from DEPARTMENT 100 only, the number of years_employed has been increased by 1 year and the file is in sorted order.
