如何解决如何在 xargs 命令中回显文件的尾部
我试图将与模式匹配的文件内容附加到另一个文件，同时将文件内容包装在标识行中。我试图在一行中执行此操作，因为我想将其添加到 logrotate 中的 prerotate 钩子中。
这是我一直在摆弄的
root@KTCH0S3HY:/opt/teamcity/logs# ls /opt/teamcity/logs/catalina.*.log | xargs -I {} echo -e "-----START {}------\n`tail
"{}" 2>&1`\n------END {}------" | tee -a test.log
-----START /opt/teamcity/logs/catalina.2021-04-08.log------
tail: cannot open '/opt/teamcity/logs/catalina.2021-04-08.log' for reading: No such file or directory
------END /opt/teamcity/logs/catalina.2021-04-08.log------
-----START /opt/teamcity/logs/catalina.2021-04-09.log------
tail: cannot open '/opt/teamcity/logs/catalina.2021-04-09.log' for reading: No such file or directory
------END /opt/teamcity/logs/catalina.2021-04-09.log------
-----START /opt/teamcity/logs/catalina.2021-04-10.log------
tail: cannot open '/opt/teamcity/logs/catalina.2021-04-10.log' for reading: No such file or directory
------END /opt/teamcity/logs/catalina.2021-04-10.log------
-----START /opt/teamcity/logs/catalina.2021-04-11.log------
tail: cannot open '/opt/teamcity/logs/catalina.2021-04-11.log' for reading: No such file or directory
------END /opt/teamcity/logs/catalina.2021-04-11.log------
-----START /opt/teamcity/logs/catalina.2021-04-12.log------
tail: cannot open '/opt/teamcity/logs/catalina.2021-04-12.log' for reading: No such file or directory
------END /opt/teamcity/logs/catalina.2021-04-12.log------
这是相同的命令，除了我拖尾完整路径而不是从 ls 命令的输出构建路径
root@KTCH0S3HY:/opt/teamcity/logs# ls /opt/teamcity/logs/catalina.*.log | xargs -I {} echo -e "-----START {}------\n`tail "/
opt/teamcity/logs/catalina.2021-04-12.log" 2>&1`\n------END {}------" | tee -a test.log
-----START /opt/teamcity/logs/catalina.2021-04-08.log------

所以该文件确实存在，但我无法遍历所有文件并将其拖尾，如第一个输出所示。
