How to copy output of commands in environment that there is no mouse to highlight and copy part of the text? like vmware console or when we stuck in grub rescue .
sorry i asked it mistakenly here instead of asking it in newbie .

usually you can use the command tee to store the output of any command (in a file) and you can use/copy that result:
<your command> | tee <filename>

thanks for reply.
if i do that then i can open it with vi to copy part of text.
is there any command in vi that i can specify exact part of the text by high lighting to copy only the high lighted part?
i now the `y` option but i should specify number of character for it .i looking for easier way.

where do you want to copy to? vi does not handle external clipboard.

ssh to the guest and you'll have commands "output" available to your local clipboard.

think that I'm going to take uuid from blkid command and use it in fstab . how can i copy the desired uuid ?
i aware of ssh but think that its not available .

in case you need that uuid on the same host you can save the output of blkid in a file, open this file and fstab in vi and you can use y (yank) and p (put) to copy lines between files and you can use :e# to switch between files.

For stuff like bootloader messages or kernel panics on real hardware, I use a camera. It also works for BIOS errors.

Same stuff on a virtual machine console can usually be done with a screen capture on the involved window.

Where a Unix-like system is running and there is hope of recovering the files afterwards, the script command is an alternative. If the files might not be savable on remote, run script locally if you can reconnect.

Basic steps:

1. run blkid and output to a temp file, optionally using awk, cut whatever to get uuid
2. vi temp file and tidy it up so it has ONLY the string you want & save it
3. edit fstab, move cursor to point of insertion, then

Code:

:r /path/to/temp.txt

r = read ; reads specified file and dumps content at current cursor position.

Unlike yank/put, doesn't require you to count lines, and text is stored in temp file on disk in case you need to redo. Any size/amt of text can be in temp file.

I think its solved by now .
the vi way looks like the easiest way.
