How to edit “Name” property in GCI output?
# Microsoft Windows [Version 10.0.17134.648]
# powershell 5.1.17134.48
# dir directory. Include index*,avail* where the last write time is less than
# 4 days. Display a parsed Name. Display the Length and the LastWriteTime.
$time = (Get-Date).AddDays(-4)
gci * -include index*,avail* | where {$_.LastWriteTime -gt $time} | format-table -HideTableHeaders Name,Length,LastWriteTime
outputs:
available13.html.2019-03-26_081523.bak 93130 3/26/2019 8 : 10 : 05 AM
index.html.2019-03-26_081538.bak 93134 3/26/2019 8 : 15 : 23 AM
I would like to change Name
to this:
available13.html 93130 3/26/2019 8 : 10 : 05 AM
index.html 93134 3/26/2019 8 : 15 : 23 AM
If I use:
$delim = "."
gci * -include *index*,*available13* -Name | `
foreach {
$nameArray = $_.Split($delim)
$newName = $nameArray[0] + "." + $nameArray[1]
Write-Output $newName
}
I get the edited Name with no date limit, no size and no last write time.
available13.html
available13.html
index.html
index.html
I've tried:
gci | gm | oh -paging
- two days of google search
- a regex (which I am not proficient at yet)
- parse
gci
outfile
It is close. Do I have to take another approach?

I'd use a RegEx with zero length lookbehind assertion to remove everything after html
from $_.Name
This can be done with a calculated property either in a Select-Object
or also in a Format-*
Get-ChildItem -File |
Format-Table @{n='foo';e={$_.Name -replace '(?<=^.*.html).*$'}},Name -HideTableHeaders
Sample output:
available13.html available13.html.2019-03-26_081523.bak
index.html index.html.2019-03-26_081538.bak

You can add a new property with Add-Member
like this
$time = (Get-Date).AddDays(-4)
$files = gci * -include index*,avail* | where {$_.LastWriteTime -gt $time}
foreach ($f in $files) {
$f | Add-Member noteproperty newName -Value `
$f.Name.Substring(0, $f.Name.Length - ".yyyy-mm-dd_iiiiii.bak".Length)
}
$files | Format-Table -HideTableHeaders newName,Length,LastWriteTime
Note that the above snippet assumes that your names always end with .yyyy-mm-dd_iiiiii.bak
. If they have some other format then you must include that information in the question, and you may need to use other string methods like replace, substring... to remove the unnecessary part
Although LotPings did not give me what I asked for, his almost solution was closest to what I ultimately needed, a solution that could be corrected into a one line shortcut. Thanks for taking the time. Yours worked right out of the box.

like this
$time = (Get-Date).AddDays(-4)
$files = gci * -include index*,avail* | where {$_.LastWriteTime -gt $time}
foreach ($f in $files) {
$f | Add-Member noteproperty newName -Value `
$f.Name.Substring(0, $f.Name.Length - ".yyyy-mm-dd_iiiiii.bak".Length)
}
$files | Format-Table -HideTableHeaders newName,Length,LastWriteTime
Note that the above snippet assumes that your names always end with .yyyy-mm-dd_iiiiii.bak
. If they have some other format then you must include that information in the question, and you may need to use other string methods like replace, substring... to remove the unnecessary part
Although LotPings did not give me what I asked for, his almost solution was closest to what I ultimately needed, a solution that could be corrected into a one line shortcut. Thanks for taking the time. Yours worked right out of the box.
