從 Cisco“show switch”輸出中刪除新行並將其與上一行連接
刪除新行並將其與上一行連接
show switch這是Cisco ACI中命令的部分範例輸出。Serial Number Name ---------------- ------------------ ABCDEFGHIJ1 XYZ_ SPN_01 ABCDEFGHIJ2 XYZ_ SPN_02 ABCDEFGHIJ3 XYZ_ SPN_03我嘗試了Merge Next Line 與上一行給出的解決方案
[user@linux ~]$ sed 'H;1h;$!d;g;s/\n */ /g' sample.txt Serial Number Name ---------------- ------------------ ABCDEFGHIJ1 XYZ_ SPN_01 ABCDEFGHIJ2 XYZ_ SPN_02 ABCDEFGHIJ3 XYZ_ SPN_03 [user@linux ~]$它幾乎提供了我想要的輸出，除了裡面有額外的空間。
所需輸出 1
Serial Number Name ---------------- ------------------ ABCDEFGHIJ1 XYZ_SPN_01 ABCDEFGHIJ2 XYZ_SPN_02 ABCDEFGHIJ3 XYZ_SPN_03當我嘗試使用
show switch具有更多列的實際輸出時，就會發生實際問題。[user@linux ~]$ cat output.txt ID Pod Address In-Band IPv4 In-Band IPv6 OOB IPv4 OOB IPv6 Version Flags Serial Number Name ---- ---- --------------- --------------- ------------------------- --------------- ------------------------- ------------------ ----- ---------------- ------------------ 101 1 192.168.1.10 0.0.0.0 :: 10.1.1.10 :: n9000-13.0(2n) asiv ABCDEFGHIJ1 ABC_ SPN_01 102 1 192.168.1.11 0.0.0.0 :: 10.1.1.11 :: n9000-13.0(2n) asiv ABCDEFGHIJ2 ABC_ SPN_02 103 1 192.168.1.12 0.0.0.0 :: 10.1.1.12 :: n9000-13.0(2n) asiv ABCDEFGHIJ3 ABC_ SPN_03 [user@linux ~]$

sed '1,2!{N;s/[[:blank:]]*\n[[:blank:]]*//;}' file在範圍 1-2 之外的每一行上：
- 將下一行附加到模式空間
- 刪除前導/尾隨空格
告訴我這是否適合你：
