Hello,

There are directories named by "yyyyMMdd" format. The one directory name is given and I should find & print that directory & its previous days directory names if exist.

For example:

20080401
20080402
20080403
20080404
...

The given date: 20080403

The result:
20080403
20080401
20080402

Thanks in advance

Sounds like homework. Read the TOS.

If it's not homework, care to elaborate?

Hi,

If you have all the dates in a file called dates1 , then

awk ' $1 <= 20080403 ' dates1

20080401
20080402
20080403

Thanks penchal_boddu,

I could do it by writing few lines of code, but I wanted to do it in one line. I wrote by the following way, it works, except for new line & space character. How can I remove new line & space characters?

Thanks a lot

[testuser@localhost proc]$ find -type d

Thanks all,

[testuser@localhost proc]$ find -type d | sed "s#^.##" | sed "s#/##" | sed '/^$/d' | sort -k1 -u | awk '$1<=20080403'
20080401
