bash -x 如何打印出时间戳

dolinux

HI，各位
RT，在执行脚本的时候，用 bash -x 可以打印出脚本详细的执行过程，现在有个问题，如何在打印详细过程的时候同时打印出脚本中
每条命令执行的时间？

比如：
$ cat test.sh
#!/bin/bash
echo "hello"
echo "world"

bash -x test.sh
{2012-02-29 18:00:00} + echo hello
{2012-02-29 18:00:01} hello
{2012-02-29 18:00:02} + echo world
{2012-02-29 18:00:03} world

1. bash -x temp.sh 2>&1 | sed -u 'h;s/.*/date/e;G;s/\n/ : /;'

可以这样搞硬PS4。

1. 
   
2. $ PS4='\d \t+ '
   
3. 
   
4. $ set -x
   
5. 
   
6. $ for i in t*.txt ;do echo $i;done
   
7. Wed Feb 29 20:27:02+ for i in 't*.txt'
   
8. Wed Feb 29 20:27:02+ echo test.txt
   
9. test.txt
   
10. Wed Feb 29 20:27:02+ for i in 't*.txt'
    
11. Wed Feb 29 20:27:02+ echo tt67.com.txt
    
12. tt67.com.txt

找到解决方法了，如下：

mengalong@ubuntu:/tmp$ cat a.sh
#!/bin/bash
export PS4='+ [$USER@\H \w ${BASH_SOURCE[0]}LINENO ${FUNCNAME[0]} \D{%F %T}]\$'
source func.sh
function tt
{
        for i in `seq 0 3`
        do
                echo $i
        done
}
echo hello
tt
aa


mengalong@ubuntu:/tmp$ bash -x a.sh
+ export 'PS4=+ [$USER@\H \w ${BASH_SOURCE[0]}LINENO ${FUNCNAME[0]} \D{%F %T}]\$'
+ PS4='+ [$USER@\H \w ${BASH_SOURCE[0]}LINENO ${FUNCNAME[0]} \D{%F %T}]\$'
+ [mengalong@ubuntu /tmp a.sh:3  2012-02-29 04:45:58]$source func.sh
+ [mengalong@ubuntu /tmp a.sh:11  2012-02-29 04:45:58]$echo hello
hello
+ [mengalong@ubuntu /tmp a.sh:12  2012-02-29 04:45:58]$tt
++ [mengalong@ubuntu /tmp a.sh:5 tt 2012-02-29 04:45:58]$seq 0 3
+ [mengalong@ubuntu /tmp a.sh:6 tt 2012-02-29 04:45:58]$for i in '`seq 0 3`'
