How to omit heading in df -k command of SunOs
提问by AabinGunz
Input: df -k
输入： df -k
Output:
输出：
Filesystem kbytes used avail capacity Mounted on
/dev/dsk/c0t0d0s0 10332220 443748 9785150 5% /
/devices 0 0 0 0% /devices
ctfs 0 0 0 0% /system/contract
proc 0 0 0 0% /proc
mnttab 0 0 0 0% /etc/mnttab
swap 45475864 1688 45474176 1% /etc/svc/volatile
objfs 0 0 0 0% /system/object
sharefs 0 0 0 0% /etc/dfs/sharetab
/dev/dsk/c0t0d0s3 10332220 3513927 6714971 35% /usr
I want to omit the 1st line Filesystem kbytes used avail capacity Mounted onfrom the output.
我想Filesystem kbytes used avail capacity Mounted on从输出中省略第一行。
I used df -k | tail -n+2in linux to get exactly what i wanted, but in SunOs I get
我df -k | tail -n+2在 linux 中使用以获得我想要的东西，但是在 SunOs 中我得到了
zenvo% df -k | tail -n+2
usage: tail [+/-[n][lbc][f]] [file]
tail [+/-[n][l][r|f]] [file]
How can i achieve the Required output:

I haven't used SunOS but using sed you should be able to delete the first line like this:
我没有使用过 SunOS，但使用 sed 你应该能够像这样删除第一行：
df -k | sed -e /Filesystem/d
edit: But you would have to be careful that the word Filesystem doesn't show up elsewhere in the output. A better solution would be:
编辑：但是你必须小心，文件系统这个词不会出现在输出的其他地方。更好的解决方案是：
df -k | sed -e /^Filesystem/d

What about:
关于什么：
df -k | tail -$((`df -k | wc -l`-1))

I know it's an old thread, but the shortest and the clearest of all:
我知道这是一个旧线程，但最短和最清晰：
df -k | sed 1d
