-rwxr-xr-x 1 oracle dba  222 Nov 11  2021 perf_pyia_job.json
-rwxr-xr-x 1 oracle dba  244 Sep 22  2016 perf_pyia_joblong.json
-rwxr-xr-x 1 oracle dba  233 Aug  8  2022 perf_pyia_logswitches.json
-rwxr-xr-x 1 oracle dba  244 Sep 22  2016 perf_pyia_object.json
-rwxr-xr-x 1 oracle dba  228 Sep 22  2016 perf_pyia_rmanbackup.json

[oracle@gsierp conf]$ cat ./* |grep database
"database":"pyia"
"database":"pyia"
"database":"pyia"
"database":"pyia"
"database":"pyia"
"database":"pyia"
"database":"pyia"
"database":"pyia"
"database":"pyia"
"database":"pyia"

2.1 替换文件名

for i in ./perf_pyia_*; do mv $i "$(echo "$i" | sed 's/perf_pyia/perf_PCMSMES/')" ; done

2.2 替换文件内容
