The prototypical append-only data structure is the log file. Log-structured data structures found in Log-structured file systems and databases work in a similar way: every change (transaction) that happens to the data is logged by the program, and on retrieval the program must combine the pieces of data found in this log file.

PowerShell 7 is the replacement for PowerShell Core 6.x products as well as Windows PowerShell 5.1, which is the last supported Windows PowerShell version. [ 110 ] [ 108 ] The focus in development was to make PowerShell 7 a viable replacement for Windows PowerShell 5.1, i.e. to have near parity with Windows PowerShell in terms of compatibility ...
atime record is not modified when file is read/accessed. Append-only a +a,-a: Writing to file only allowed in append mode. Immutable i +i,-i: Prevents any change to file's contents or metadata: file/directory cannot be written to, deleted, renamed, or hard-linked. No dump d +d,-d: File is skipped by the dump program: Secure deletion s +s,-s
/A Append the pipeline content to the output file(s) rather than overwriting them. Note: When tee is used with a pipe, the output of the previous command is written to a temporary file. When that command finishes, tee reads the temporary file, displays the output, and writes it to the file(s) given as command-line argument.
In computer programming, foreach loop (or for-each loop) is a control flow statement for traversing items in a collection. foreach is usually used in place of a standard for loop statement.
This simple control table directs program flow according to the value of the single input variable. Each table entry holds a possible input value to be tested for equality (implied) and a relevant subroutine to perform in the action column. The name of the subroutine could be replaced by a relative subroutine number if pointers are not supported
add a new (,) pair to the collection, mapping the key to its new value. Any existing mapping is overwritten. The arguments to this operation are the key and the value. Remove or delete remove a (,) pair from the collection, unmapping a given key from its value. The argument to this operation is the key.
The specification for pass-by-reference or pass-by-value would be made in the function declaration and/or definition. Parameters appear in procedure definitions; arguments appear in procedure calls. In the function definition f(x) = x*x the variable x is a parameter; in the function call f(2) the value 2 is the argument of the function. Loosely ...
