But when I put that command on cron job, even I run “. /etc/profile” and

“.

~/.bash_profile” first, I can’t get correct format of output.

% has a special meaning in a crontab. See man 5 crontab.

I warped this command in script and trigger script in crontab.
I think it's not the root cause, because %ae still works.

I notice that the only placeholder that is broken is %aN, which converts
using the .mailmap file. Maybe something in your environment is
preventing reading that file properly?

$ ll .mailmap
-rw-r--r-- 1 wangchen club 4021 Oct 15 06:18 .mailmap

Can you show us the exact script you're calling from your crontab file?
I'm wondering if it's something to do with being in the same directory.

Sure.
$ crontab -l
58 06 * * * /home/wangchen/kps_update
$ cat /home/wangchen/kps_update
#!/bin/bash
su wangchen -
. /etc/profile
. ~/.bash_profile
cd /home/wangchen/kps
git pull
make
cd /home/wangchen/linux-2.6
git pull
/home/wangchen/kps/kps_web/kps_do /home/wangchen/linux-2.6 /home/wangchen/kps
$ cat /home/wangchen/kps/kps_web/kps_do
#!/bin/sh
#check script parameters
if [ -r $1 -a -w $2 ]; then
        echo "begin to update kps_result"
        readonly LGP=$1
        KGP=$2
        KGP=${KGP%%/}
else
        echo "usage: $0 linux_kernel_source_dir kps_source_dir"
        exit 1
fi
