求助:echo丢失回车并且只有最后一行

Below is the debug info, hope some one can help me to understand, thank you!

+ echo 87%

这是调试信息.最后的输出只有一行.
78% /a/nyn101f2/vol/nyn101f2v5/appl_fx_tieredpricing_data_latency_01_new
我预期的输出是:
3% /
0% /dev/vx
52% /afscache
0% /dev/shm
0% /ms
100% /tmp_ns
100% /tmp_amd
66% /a/nyn67f1/vol/nyn67f1v1/r_ied_asgna_new
1% /var/VRTSvcs/lock
29% /d/ny0251fx01/d1
65% /a/nyn74f1/vol/nyn74f1v4/r_it_fxprod
90% /a/hkn8f1/vol/hkn8f1v3/u_t1332939396
78% /a/nyn101f2/vol/nyn101f2v5/appl_fx_tieredpricing_data_latency_01_new

From the debug info we can see that the variable spaceUsedPercent has got the value, but why the eventual output only left the last line?

能否把完整代码贴出来看看？

    我换了个思路避开了这个问题。谢谢你哈。我自己再理解下！非常感谢

应该是输出的内容有 \r 的原因？
