Bash scripts tend to use transformation programs that accept input through standard input and use the output from standard output. For replacing one character with another, the "tr" program is typically used.

To operate on the command-line arguments to a program like "mv", bash allows you to use back-tick quotes.

 undefined

    
set FNAME="path/bad:file\\name"
mv "$FNAME" `echo "$FNAME" | tr ":\\" "_-"`

  

Note the use of escaped backslashes... the pair represents a single charcter. Be sure to study the manual for each command (e.g. man tr) before using it at first.

Te experiment building this kind of complicated command, replace the "mv" with "echo" to see what the two constucted arguments will be, and switch back to "mv" when they look right.

One approach to looping is to turn the above into a script that fixes one filename specified as an argument to the script ($1 inside the script) and then interactively pipe all the filenames through xargs to give them one at a time to your script.

 undefined

    
find topdir -type f | xargs -d "\n" yourscriptname

  

You must try this on sample data and also backup your current data before turning your script loose on it... so often there are little things that don't behave the way you expect when some unexpected input interacts with your script.

Finally, there are scripting languages like Python that have a lot of these capabilities built in... and with more consistent syntax than the many-tools bash approach, but they can have the headache of a lot more specialized setup requirements than just bash to go along with those advantages.

Bro stair climbing wheelchair. Segway put a lot of design effort into this about 30 years ago before trying to go big with the normal Segway. https://www.scewo.com/en/

I copied so many short pieces as a child. OC is possible I suppose but there is a simpler explanation.

You didn't change anything?

No.

Where do you use it?

On my lap in the den.

When was the last time you vacuumed?

???

(Time to disassemble and apply compressed air...)

Failing to provide the name of the person in the body of the email is incomptetence.

Fox included the disclaimer about contact email... but IMO the person who built the mail merge was incompetent and that will not prevent ICE from coming after Aldo.

Not if cheeto is hiring.

This is the kind of overfitting our machine-learning overlords will find as we operate the data centers with more fossil fuels. Amazing! /s

Stick with Windows. Microft will deliver paradigm shifts and you will have no say in the matter. They are already removing options for disabling Copilot, and for all the promised backward compatibility they are letting go of features that lots of old Windows software depended on, as they introduce features similar to ones in Linux. I cannot really fault them for all of these changes, but the difference is actually one of choice and privacy, and not really the one you seem to think it is.

It is not recursive though. A directory is a special kind of inode that enumerates file inode numbers and when that list changes then the contents of that "directory inode" change. But if /home/user/.bashrc is deleted then the timestamp for /home will not be affected because the timestamps are associated with inodes rather than directory entries (assuming no symbolic links are involved).

When the choice is getting on with life or starving to death, you tend to become focused on the basics. Whether this is an improvement may be debatable (sublimation?), but sometimes life is harsh. Grandpa might have faced similar mental problems when he was young, and had no choice but to ignore them and may simply perceive that problem differently.

I, too, am not a spring chicken, so add whatever salt you like to this description. But I do think that there are a lot of hungry people around the world willing to ignore their own troubles and steal your lucky spot regardless of your mental state.

The cheeto thinks he can build walls to keep those hungry people at bay... but rather than letting them migrate to start at the bottom in the land of opportunity I think his approach is just going to end up with all of us doing more dirty work on our respective sides of the walls... possibly much sooner than we would like. Beware you don't end up out-competed in the rat race while you grapple with your internal demons.

If you convert the chemical energy in a unit of coal to heat (burn it) you can calculate how much energy exists in that coal, measured in appropriate units (e.g. kWh). That is evidently what this author is trying to dumb down as "invested energy". The amount of energy extracted as electricity is typically 40% of that.. the rest ends up as heat which is much less useful than electricity.

I agree that this is not particularly useful in discussing the merits of different energy sources because good design tends to do as well as is practical and the supply of fuel and negative impacts of that process can't vary dramatically.

When they sense invisible electromagnetic wavelengths like xrays or microwaves and "assign" colors to completely invisible wavelengths then that is false color imaging. Possible to do with the sun... but unlikely with an amateur rig.

Not OP, but solar photography requires super dense filters so like sunglasses alter what you see from "actual" the filters also alter the image from "actual" yet this is what would "actually" be "seen" by the camera. So yes and no depending how you want to interpret "actual".

Trump is the expert. I am sure he knows what he is talking about. /s

This has always been a risk for artists working for powerful people. It doesn't necessarily end well for the artist.

A policeman? is that unusual?

TIL. tho maybe TMI.

Just to second that, the model series is Latitude, not Inspiron. and yeah, the i5 processor options I got over the years beat the i7 on processing power. The Precision models are a step up, but not any kind of low cost and seem not quite as tough.
