How to copy all files into a directory and zip that directory in the Linux terminal
For example, please suppose that there are three files in the home directory: a.pdf, b.xlsx, and c.docx, and you would like to create a zip file 'abc.zip' containing the directory 'abc' with those three files.
1. Make a directory 'abc'.
$ mkdir abc
2. Copy the above three files into the directory 'abc'.
$ cp a.pdf abc
$ cp b.xlsx abc
$ cp c.docx abc
3. Zip the directory 'abc'.
$ zip -r abc.zip ./abc/
1. Make a directory 'abc'.
$ mkdir abc
2. Copy the above three files into the directory 'abc'.
$ cp a.pdf abc
$ cp b.xlsx abc
$ cp c.docx abc
3. Zip the directory 'abc'.
$ zip -r abc.zip ./abc/
To compute some values by Xcas
If you compute the following values by Xcas, then you should execute commands below. See also this page.
Case 1. One computes any maximum values for given functions with 1 parameter, for example y=x2−4x+5 for 37/19≤x≤35/17. Then, he should execute as follows. The answer must be 290/289.
Case 2. One computes any minimum values for given functions with 2 parameters, for example z=x3+y3−xy for x>0 and y>0. Then, he should execute as follows. The answer must be −1/27.
Case 3. One computes any maximum values for given 2-parameter-functions with 1 bounded condition, so-called Lagrange Multiplier method, for example z=x/2+y/3+√1−(x2/4)−(y2/9) with x+y=5√3/3. Then, he should execute as follows. The answer must be (10√3−4)/9.
Case 4. One differentiates any implicit functions such as ylnx=xlny (x>0 and y>0). Then, he should execute as follows. The answer must be (dy/dx=)(y2−xylny)/(x2−xylnx).
Case 1. One computes any maximum values for given functions with 1 parameter, for example y=x2−4x+5 for 37/19≤x≤35/17. Then, he should execute as follows. The answer must be 290/289.
maximize(x^2 - 4*x + 5, x=37/19..35/17)
Case 2. One computes any minimum values for given functions with 2 parameters, for example z=x3+y3−xy for x>0 and y>0. Then, he should execute as follows. The answer must be −1/27.
minimize(x^3 + y^3 - x*y, [x > 0, y > 0], [x, y])
Case 3. One computes any maximum values for given 2-parameter-functions with 1 bounded condition, so-called Lagrange Multiplier method, for example z=x/2+y/3+√1−(x2/4)−(y2/9) with x+y=5√3/3. Then, he should execute as follows. The answer must be (10√3−4)/9.
maximize((x/2) + (y/3) + sqrt(1 - (x^2 / 4) - sqrt(y^2/9)), x + y = 5*sqrt(3)/3, [x, y])
Case 4. One differentiates any implicit functions such as ylnx=xlny (x>0 and y>0). Then, he should execute as follows. The answer must be (dy/dx=)(y2−xylny)/(x2−xylnx).
implicitdiff(y*ln(x) = x*ln(y), y, x)

How to display the updated files within the specific period of date by "ls" command on Linux terminal
Note that your environment may differ from my environment(lubuntu). For example, if you want to find the updated files from Aug 15 to Aug 20 in 2024, then
1. move to that directory (e.g. "abcde" directory) by "cd" command.
3. execute the next "ls" command.
How to get only files created after a date with ls? - Stack Exchange Confusing use of && and || operators - Stack Exchange.
1. move to that directory (e.g. "abcde" directory) by "cd" command.
$ cd abcde2. Execute the next "ls" command.
$ ls -ltr | awk '$6 == "8月" && ($7 >=15 && $7 <= 20) && $8 = 2024 {print $6"-"$7"-"$8,$9}'
If you want to find the updated files before Aug 5 or after Aug 25 in 2024, then 3. execute the next "ls" command.
$ ls -ltr | awk '$6 == "8月" && ($7 <=5 || $7 >= 25) && $8 = 2024 {print $6"-"$7"-"$8,$9}'

How to change brightness of display on Linux terminal
To change brightness of display on Linux terminal,
1. find the display name as follows. That is "DP-2" in my case.
1. find the display name as follows. That is "DP-2" in my case.
$ xrandr --verbose2. Execute the following command.
xrandr --output (the display name) --brightness (the number between 0 and 1)For example,
xrandr --output DP-2 --brightness 0.5If the last number is close to 0 [1], then the display will be dark [bright].
