Running 7-Zip from within a Powershell script

Question

I\'m trying to use 7-Zip to backup some files inside a Powershell (v2) script.

I have:

$zipPath = \"C:\\Program Files\\7-Zip\\7z.exe\"
[Array]$zipArg         


        

Answer 1

Maybe a simpler solution is to run 7-zip on your Powershell via cmd:

cmd /c 7za ...

Answer 2

If you adapt it correctly: Dont forget the "" on "$Target" and avoid $7zipPath in c:\programm files with a space in the path

Set-Alias 7zip $7zipPath

$Source = "c:\BackupFrom\backMeUp.txt"
$Target = "c:\BackupFolder\backup.zip"

7zip a -mx=9 "$Target" "$Source"

or

7z a "$ArchiveName" -t7z '@listfile.txt'

Answer 3

put "&" special character before 7z command. Example: &7z ...

Answer 4

Simply prefix the command with an ampersand

& "C:\Program Files\7-Zip\7z.exe" -mx=9 a "c:\BackupFolder\backup.zip" "c:\BackupFrom\backMeUp.txt"

Answer 5

Found this script and adapted it to your needs. Can you please try:

$7zipPath = "$env:ProgramFiles\7-Zip\7z.exe"

if (-not (Test-Path -Path $7zipPath -PathType Leaf)) {
    throw "7 zip file '$7zipPath' not found"
}

Set-Alias 7zip $7zipPath

$Source = "c:\BackupFrom\backMeUp.txt"
$Target = "c:\BackupFolder\backup.zip"

7zip a -mx=9 $Target $Source

Answer 6

try to use parameter -file to specify the location of program or script:

-file "C:\Program Files\someting.exe"
