奇怪的问题

db2inst1@serv30:/home/db2inst1# echo $(db2 list tablespace containers for 1)
Tablespace Containers for Tablespace 1 Container ID = 0 Name = /db/db2inst1/db2data/MAD/db2inst1/NODE0000/TPCD/T0000001/C0000000.TMP Type = Path
db2inst1@serv30:/home/db2inst1# echo $(db2 list tablespace containers for 1|grep Name)

db2inst1@serv30:/home/db2inst1#
db2inst1@serv30:/home/db2inst1# echo $?
0
db2inst1@serv30:/home/db2inst1#

加grep后为啥结果为空呢？

你确认没写错？不会有不可见字符？

没有不可见字符。
db2inst1@serv30:/home/db2inst1#db2 list tablespace containers for 1|grep Name
Name                                 = /db/a3inmadp/db2data/MAD/a3inmadp/NODE0000/TPCD/T0000001/C0000000.TMP
