我有两个文件，想逐行合并数据。输入文件是 file.txt 和 file2.txt。

file1.txt

howareu
abc
zooo

file2.txt

123
@@
099

我想合并这两个文件，这样输出将是：

output.txt

howareu123
howareu@@
howareu0999
abc123
abc@@
abc0999
zooo123
zooo@@
zooo0999

有没有办法做到这一点？有没有办法使用sedorpaste命令来获取结果？

我尝试运行应用程序“KDevelop”，但返回以下错误：

我还删除并重新安装了 KDevelop，但返回相同的错误。

我正在使用 Ubuntu 16.04 并希望访问/使用服务器中的不同磁盘（以下磁盘）：

我只能访问/使用以下内容：

tmpfs                      26G     0   26G   0% /run/user/1000

我也尝试以下方法：

sudo fdisk /dev/sdc

Welcome to fdisk (util-linux 2.27.1).
Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.

Device does not contain a recognized partition table.
The size of this disk is 5.5 TiB (6001175126016 bytes). DOS partition table format can not be used on drives for volumes larger than 2199023255040 bytes for 512-byte sectors. Use GUID partition table format (GPT).

Created a new DOS disklabel with disk identifier 0x2a4732aa.

我怎样才能使用其他磁盘sdc，，sdd...sdf

我在 Ubuntu 2016.04.5 上安装 Petalinux_v2018.2

./petalinux-v2018.2.ir.run /opt/petalinux_2018.2/

但以错误结束：

./petalinux-v2018.2.ir.run: line 52: /opt/petalinux_2018.2/petalinux_installation_log: Permission denied
tee: /opt/petalinux_2018.2/petalinux_installation_log: Permission denied

Please refer to the PetaLinux Tools Installation Guide.

Check the troubleshooting guide at the end of that manual, and if you are
unable to resolve the issue please contact customer support with file:
   /opt/petalinux_2018.2/petalinux_installation_log

tee: /opt/petalinux_2018.2/petalinux_installation_log: Permission denied

ERROR: Failed to extract the PetaLinux installer. Failed to install PetaLinux Tools!

任何解决此问题的帮助将不胜感激。

当我尝试

sudo ./petalinux-v2018.2.ir.run /opt/petalinux_2018.2/

它还提示错误：
