LinuxQuestions.org - linux-related notes

Just annotations of little "how to's", so I know I can find how to do something I've already done when I need to do it again, in case I don't remember anymore, which is not unlikely. Hopefully they can be useful to others, but I can't guarantee that it will work, or that it won't even make things worse.

Pay attention to ";" versus "&&" in bash aliases

Or maybe avoid it altogether, it's probably some sort of well known linux/unix rule that someone wrote a long time ago.

It's possibly something that seldom ever is a problem to anyone, but it was for me.

I had this as an alias for "mv"

Code:

echo "use mv -i to avoid overwriting files with the same name; this is an alias to mv -i" ; mv -i

Then at some point I was doing an one liner that would scan symlinks' "realpaths"...

The "sed" command doesn't need quotes

You may have some trouble when trying to make sed replacements along the lines of:

sed 's|$originalpath|$otherpath/$filename|'

If the variables contain things like the "-" character, or some other special characters, some of the sed commands may be terminated before they should, in error, as it's taking part of the variable as sed commands, rather than parameters. Something like that. Then the variables would ideally be quoted, but with the outermost quotes,...

A sequel to my topic, "onboard video card dying, or something else?", where Shadow_7 posted:

I had a bad cap on an asus rt-n16. One of my old motherboards had a similarly spec'd cap that I replace it with. $80 saved.

If the bad caps are on the motherboard, a new video card wont save it.

Out of curiosity,...

Annotations while trying to eventually get suspension and/or hibernation to work

I've never used this kind of thing, decided to give a try, as it seemed safe for all I was reading.

"pm-suspend-hybrid" did work, but after resuming, the CPU fan was reset to full speed all the time, as if the BIOS was set to have "smart fan control" disabled.

It may be also partly because some of the power management options (whatever is its name) are set to "S3" which I recall reading isn't really appropriate for suspension (which keeps...

Stylish CSS userstyle for new google's image search, so you can spare an extra click

It's crude but seems to work. I simply don't get why webdesigners think it's a great idea to needlessly hide small menus under that "vertical ellipsis" icon. At very least those could be displayed just by hovering.

Code:

.irc_m {
    background-color: #fff;
    box-shadow: 3px 3px 12px rgba(0,0,0,0.4);
    margin-top: 0px;
    overflow: auto;
    padding: 0px 0;
    position: absolute;
    right: 8px;
    z-index: 2;
