Heads and Tails - 尝试获取每个文件的第一行和最后十行
我有一个输出文件目录，我想按顺序显示每个文件的第一行和最后十行。
我已经得到了部分命令：
ls output/*Response | sort -t_ --key=2 -g | xargs tail | less
这给了我这样的东西：
==> output/Acdb_18_Response <==
150707,"SOVO","Other","","","","","","160x600",0,0,1432,0,0,1432
167493,"Asper","Other","","","","","","160x600",143200,0,0,1432,0,0
269774,"AIKA","Other","","","","","","160x600",0,1432,0,0,1432,0
342275,"Lorrum","Other","","","","","","160x600",0,0,1432,0,0,1432
347954,"Game","Other","","","","","","160x600",0,1432,0,0,1432,0
418858,"Technologies","Other","","","","","","160x600",0,1432,0,0,1432,0
24576,"Media ","Other","","","","","","300x600",0,0,1432,0,0,1432
23351," Plus","Other","","","","","","425x600",0,4296,0,0,4296,0
#rowcount=79
这很好，但我想包含第一行来获取标题。我尝试将输出连接到头部，但到目前为止我还无法弄清楚如何排列管道。
有什么建议吗？
I've got a directory of output files that I'd like to display the first line of each file and the last ten lines of each file in order.
I've got part of the command down:
ls output/*Response | sort -t_ --key=2 -g | xargs tail | less
Which give me something like this:
==> output/Acdb_18_Response <==
150707,"SOVO","Other","","","","","","160x600",0,0,1432,0,0,1432
167493,"Asper","Other","","","","","","160x600",143200,0,0,1432,0,0
269774,"AIKA","Other","","","","","","160x600",0,1432,0,0,1432,0
342275,"Lorrum","Other","","","","","","160x600",0,0,1432,0,0,1432
347954,"Game","Other","","","","","","160x600",0,1432,0,0,1432,0
418858,"Technologies","Other","","","","","","160x600",0,1432,0,0,1432,0
24576,"Media ","Other","","","","","","300x600",0,0,1432,0,0,1432
23351," Plus","Other","","","","","","425x600",0,4296,0,0,4296,0
#rowcount=79
which is nice but I'd like to include the first line to get the header. I tried tee'ing the output to head but so far I haven't been able to figure out how to arrange the pipes.
Any suggestions?
