JSI Tip 9055. What command will return the folders in my PATH, one per line?JSI Tip 9055. What command will return the folders in my PATH, one per line?

Making use of Environment Variable string substitution syntax, and the FOR %variable IN (set) DO command command, you can use the command-line, or a batch, to display the folders in your %PATH%, one per line:

Command-line

for %f in ("%PATH:;=" "%") do @echo %f

Batch

for %%f in ("%PATH:;=" "%") do @echo %%f

If you wish to also strip the encapsulating quote marks ("), you can add parameter parsing:

Command-line

for %f in ("%PATH:;=" "%") do @echo %~f

Batch

for %%f in ("%PATH:;=" "%") do @echo %%~f

Examples:

If your %PATH% contains:

C:Program FilesWindows Resource KitsTools;C:WIN_ONE;C:WINDOWSsystem32;C:WINDOWS;C:WINDOWSSystem32Wbem;C:UTIL

Typing for %f in ("%PATH:;=" "%") do @echo %f would return:

"C:Program FilesWindows Resource KitsTools""C:WIN_ONE""C:WINDOWSsystem32""C:WINDOWS""C:WINDOWSSystem32Wbem""C:UTIL"

while typing for %f in ("%PATH:;=" "%") do @echo %~f would return:

C:Program FilesWindows Resource KitsToolsC:WIN_ONEC:WINDOWSsystem32C:WINDOWSC:WINDOWSSystem32WbemC:UTIL

NOTE: What is happening with ("%PATH:;=" "%"):

1. The leading " inserts a quote mark at the beginning of the set.

2. The %PATH:;=" "% replaces all ;s with " ", defining the end of each folder path and the beginning of the next.

3. The trailing " inserts a quote mark at the end of the set.
