One of the situations where setlocal enabledelayedexpansion comes on handy to replace \ with / which some unix based tools like better: [WayBack] string – Change backslash to forward slash in windows batch file – Stack Overflow
echo off
setlocal enabledelayedexpansion
for %%f IN ("C:\tools\workspace\*") DO (
set old=%%f
echo !old!
set new=!old:\=/!
echo !new!
echo.
)
Related, as it explains when the source and target replacements are in variables themselves: [WayBack] command line – String replacement in batch file – Stack Overflow, thanks Joey and Tom Warfield!
You can use the following little trick:
set word=table
set str="jump over the chair"
call set str=%%str:chair=%word%%%
echo %str%
The call there causes another layer of variable expansion, making it necessary to quote the original % signs but it all works out in the end.
…
Upvoting this answer because it works both ways, with the environment variable in either position, or in both the “before” and “after” positions:
set word=table
set str="jump over the chair"
call set str=%%str:chair=%word%%%
echo %str%
set word1=chair
set word2=desk
set str="jump over the chair"
call set str=%%str:%word1%=%word2%%%
echo %str%'

Last week, I wrote about a bit of my command-line and scripting history at I wanted to know the loaded DLLs in a process like Process Explorer shows, but from the console: Sysinternals ListDLLs to the rescue.
Since information about VMS and DCL is harder to find nowadays, I saved some information in the wayback machine:
By now, there should be a good x86_64 version of OpenVMS, so this is also a reminder to self to see if that can run as a VM and is affordable enough to do some experimentation with.

From my batch file library; note this PowerShell wrapper does not support stdin, but that is OK for me.
For Windows 10 and up, sort /unique works too and supports stdin.
:: note: does not work on stdin, unliqke sort which does support standard input
:: http://secretgeek.net/ps_duplicates
PowerShell Get-Content %1 ^| Sort-Object ^| Get-Unique
:: note that for Windoww 10 and up, there is a sort /unique switch, but Windows versions below it do not.

A while ago I found out that choco upgrade will install a package when it is not installed, and that choco upgrade all will upgrade all installed packages.
So I looked up the documentation of both choco install and choco upgrade (and choco update which will be deprecated) where I bolded parts of the upgrade command:
Given that upgrade can do both an upgrade and an install, I have switched all my install scripts to use upgrade in steaf of install.

- Almost all log files (most from
/var/log and all from /var/run/log) are actually persistently stored in /scratch/log and survive reboots. Just a few are non-persistent.
/var/log/syslog is being archived as .gz files (compressed by gzip).syslog is special: the location can be configured, and even be external: [Wayback] Configuring syslog on ESXi (2003322)
VMware vSphere ESXi 5.0 and higher hosts run a Syslog service (vmsyslogd) that provides a standard mechanism for logging messages from the VMkernel and other system components. By default in ESXi, these logs are placed on a local scratch volume or a ramdisk. To preserve the logs further, ESXi can be configured to place these logs to an alternate storage location on disk and to send the logs across the network to a Syslog server.
- A summary of some of the above log files is at [Wayback] ESXi Log File Locations
