I know how to convert from UNIXTIME to DATETIME, but I've never done the reverse. I've used FROM_UNIXTIME, is there no TO_UNIXTIME? 回答1: It's UNIX_TIMESTAMP . This will take a properly formatted datetime as an argument. 回答2: It's okay, I figured it out. I had 'article_date' for the original column. I created 'new_date' for the new column. Then I did: UPDATE news SET new_date = UNIX_TIMESTAMP(article_date)

I'm having trouble writing a script to rename the files so that all of the file names use only ASCII characters. I think that using the iconv command should work, but I'm having trouble escaping the characters for the 'mv' command. EDIT: It doesn't matter if there isn't a direct translieration for the unicode chars. I guess that i'll just replace those with a "?" character. 回答1: I don't think iconv has any character replacement

This looks like an unusual function signature, but in my particular situation, the keys and values in these maps will be of the same type. template < typename T , int N > map < T , T > array_to_map ( T (& a )[ N ][ 2

I figure this would be done with a script, but what language should I use, and how would I go about unzipping and rezipping files? 回答1: I'd do it with a bash(1) one-liner: for f in *.tar.gz;\ do rm -rf ${f%.tar.gz} ;\ mkdir ${f%.tar.gz} ;\ tar -C ${f%.tar.gz} zxvf $f ;\ zip -r ${f%.tar.gz} $f.zip ;\ rm -rf ${f%.tar.gz} ;\ done It isn't very pretty because I'm not great at bash(1) . Note that this destroys a lot of directories so be sure
