Thank you Corona688
I follow yours instructions.

I put an error in the first line (13 for the month)
Code:
cat inputfile
2013-13-31 12 05
2012-12-01 05 24
2011-02-21 09 15

When i launch the script, there are malfunctions.
1) Each line with right or wrong paramaters are printed twice.
I would like the line that has an error is not edited.
It should only return the error code.
And others to be edited once.


Can you correct this script ?
Thank you in advance.

Code:
./my_script inputfile
Fatal, $1 = '2013-13-31', Date not conform OR absent
Errors found in date/time - exiting now
2013-13-31 12 05 line 1
2012-12-01 05 24 line 2
2011-02-21 09 15 line 3
2013-13-31 12 05 line 1
2012-12-01 05 24 line 2
2011-02-21 09 15 line 3
