-`%F`, full date in ISO 8601 format; like ‘%+4Y-%m-%d’ except that any flags or field width override the ‘+’ and (after subtracting 6) the ‘4’. This is a good choice for a date format, as it is standard and is easy to sort in the usual case where years are in the range 0000…9999.
- You can use `sed` to remove the first line of the output.
```console
$ ./files-details.sh # without using sed
total
-rw-rw-r-- 2022-12-20 03:10:18 README.md
$ ./files-details.sh # using sed
-rw-rw-r-- 2022-12-20 03:10:18 README.md
$
```
-`awk`.
You can specify specific column names to display or include in the awk output using the field numbers. For example:
```console
$ ls -l | awk '{print $1, $2, $3, $4, $5, $6, $7, $8, $9, $10}' # print all the given fields
total 4
-rw-rw-r-- 1 user user 1989 dez 20 15:19 README.md
$ ls -l | awk '{print $1, $2, $4, $5, $7, $8, $10}' # print all the given fields
total 4
-rw-rw-r-- 1 user 2350 20 15:25
$
```
awk ‘{print $1}’ emp_records.txt
awk {print $1, $6, $7, $8, $9, $10}'
