Insert year in ls -l command
Hi All,
Have a file where i stored ls -l command output,
Code:
-rw-r--r--    1 360      600         94255 Jan 01 11:16 file1_2020.csv
-rw-r--r--    1 360      600        114573 Dec 29 11:10 file2_2019.csv
-rw-r--r--    1 360      600         41006 Dec 30 11:09 file3_2019.csv
-rw-r--r--    1 360      600        165923 Dec 31 11:29 file4_2019.csv

Want to extract year from filename and insert in every respective line, output should be:
Code:
-rw-r--r--    1 360      600         94255 Jan 01 11:16 2020 file1_2020.csv
-rw-r--r--    1 360      600        114573 Dec 29 11:10 2019 file2_2019.csv
-rw-r--r--    1 360      600         41006 Dec 30 11:09 2019 file3_2019.csv
-rw-r--r--    1 360      600        165923 Dec 31 11:29 2019 file4_2019.csv

Can this be possible using awk and sed in one line instead of running any for loop.

**I got this output from ftp server, and that is why cannot use ls --fu command to get year. That is why i thought of appending year after getting filenames to local server, If there is any alternative for this kindly let me know

       no operands are specified, a calendar for the current month is written.

OPERANDS

       The following operands are supported:

       month	Specify the month to be displayed, represented as a decimal integer from 1 (January) to 12 (December). The default is the  current
		month.

       year	Specify  the year for which the calendar is displayed, represented as a decimal integer from 1 to 9999. The default is the current
		year.

ENVIRONMENT VARIABLES

       See  environ(5) for descriptions of the following environment variables that affect the execution of cal: LANG, LC_ALL, LC_CTYPE,  LC_TIME,
       LC_MESSAGES, and NLSPATH.

       TZ    Determine the timezone used to calculate the value of the current month.

EXIT STATUS

NOTES

       An  unusual calendar is printed for September 1752. That is the month 11 days were skipped to make up for lack of leap year adjustments. To
       see this calendar, type:

	 cal 9 1752

       The command cal 83 refers to the year 83, not 1983.

       The year is always considered to start in January.
