powershell - Boolean test if an archive is corrupt -


after creating zip file, i'd add confirmation if successful.

start-process -filepath "$env:zroot\7z.exe" -argumentlist "t d:\mybackup\log5.zip *.* -r" -wait -passthru

i output:

 handles  npm(k)    pm(k)      ws(k) vm(m)   cpu(s)     id processname                                                                                                                                                                                               -------  ------    -----      ----- -----   ------     -- -----------                                                                                                                                                                                               4       2      248       1088     6     0.02  10236 7z

how capture boolean test command line, if zip file corrupt?

you don't need start-process. run command , check $lastexitcode variable (i.e., exit code of executable). per 7-zip documentation, non-zero exit code indicates error. example (not tested):

& $(join-path $env:zroot "7z.exe") t "d:\path name\whatever.zip" if ( $lastexitcode -ne 0 ) { "there error" }
