建议的解决方案

DUMPFILE=mydump.sql
grep "^USE " ${DUMPFILE} | sed 's/;//' | sed 's/`//g' | awk '{print $2}'

例子

# grep "^USE " dump.sql | sed 's/;//' | sed 's/`//g' | awk '{print $2}'
CR1281653
CR1289379
MasterDB
ProjectDB
TPLB23
a110107
a110107_copy
cardfree_orders_lab
mysql
nulldatetest

您可以将它们收集在变量中（注意：您必须转义反引号）

# DBLIST=`grep "^USE " dump.sql | sed 's/;//' | sed 's/\`//g' | awk '{print $2}'`
# echo ${DBLIST}
