how's it going, everything alright? I need to build a script that controls the space of a particular FS which has several directories. On the other hand, it will be necessary to send an email indicating the percentage of occupancy of each Directory and within that FS, on the total occupancy indicating what percentage of the total space each directory occupies. What I am particularly in need of is how I can perform those calculations.

For example, I detail the name of the FS and what each directory occupies

FS : /archivos (5T)
Contenido: /archivos/test/ (1T)
Contenido: /archivos/garbage/ (10 Megas)
Contenido: /archivos/log/ (2T)
Contenido: /archivos/solaris/ (5 kilobytes)

lo que necesitaria es que me muestre algo asi

/archivos -> Ocupoa 5Teras, ocupado 90%
/archivos/test/ (1T), ocupa el 20% del FS /archivos
/archivos/garbage/ (10 Megas), ocupa el 1% del FS /archivos
/archivos/log/ (2T), ocupa el 30% del FS /archivos
/archivos/solaris/ (5 kilobytes), ocupa el 1% del FS /archivos

How can I get that data and calculate the percentage as I need it?

This must be in bash

people how are you

How can I do to automatically rename a list of files, only modifying the date that it has in the name of the file, for the current day, without modifying the rest of the values??

I have a file that has the list, its content would be like this:

DASH_20210608175132_0000.msg
DASH_20210608175132_0001.msg
DASH_20210608175132_0002.msg

Manually it would be:

mv DASH_20210608175132_0000.msg DASH_`date +"%Y%m%d"`175132_0000.msg
mv DASH_20210608175132_0001.msg DASH_`date +"%Y%m%d"`175132_0001.msg
mv DASH_20210608175132_0002.msg DASH_`date +"%Y%m%d"`175132_0002.msg
mv DASH_20210608175132_0003.msg DASH_`date +"%Y%m%d"`175132_0003.msg

In this way I only change what I need the date in the file mask.

But I would like to automate this procedure, how could I do it?

I have the text SAR_aPP.D7HG32689 , and I only want to get the last 4 characters, in this case it would be 2689 , but it can be something else, since the text is random and the total number of characters can also vary.

How can I get this with sed?

I tried with:

$ sed 's/SAR_aPP.//g'

To remove the first part, but what follows I have no idea.

I tried with: cut -c, but I could only see that it strips characters from front to back, or it won't use it correctly.

How are you doing. I have a file that has 5 fields separated by pipes

Example:

0987123443|InfoBasica||Derivación Proceso|8899776673|Cliente 10001144795 no existe.|

In which the last field, in this example would be "Client 10001144795 does not exist." is the error message. The errors are not always the same and new errors may appear. What you would need is that every time a new error is found, that last field is added to a file. The file that contains errors does not always have the same number of lines, so one day 10 may appear, other times 900, and so on.

More in detail the file could come like this:

0987123443|InfoBasica||Derivación Proceso|8899776673|Cliente 10001144795 no existe.|
3246656545|InfoBasica||Derivación Proceso|6587678778|Cliente 12341241243 duplicado.|
3457878784|InfoBasica||Derivación Proceso|5486787867|Cliente 45675467456 duplicado.|
2345326654|InfoBasica||Derivación Proceso|0987090909|Cliente 34543254545 no existe.|

How can I do it in Linux?
