Remove Top Line of Text File with Powershell

Question

I'll be honest I feel dumb about this one. I am trying to just remove the first line of about 5000 text files before importing them.

I am still very new to powershell so not sure what to search for or how to approach this. My current concept using pseudo-code

set-content file (get-content unless line contains amount)

However, I can't seem to figure out how to do something like contains. I tried a couple of other methods, but feel like I am chasing my tail for an easy problem.

Thanks for any help.

Answer 1

Not the most efficient in the world, but should work:

get-content $file |
    select -Skip 1 |
    set-content "$file-temp"
move "$file-temp" $file -Force

Answer 2

Using variable notation, you can do it without a temp file.

${C:\file.txt} = ${C:\file.txt} | select -skip 1
function Remove-Topline ( [string[]]$path, [int]$skip=0 ) { if ( (Test-Path $path -PathType Leaf) -like 'false') { throw "invalid filename" } else { ls $path | % { iex "${$($_.fullname)} =${$($_.fullname)} | select -skip $skip" } } }

Answer 3

Hello for me also -skip didn't work, so my workaround is $LinesCount = $(get-content $file).Count get-content $file | select -Last $($LinesCount-1) | set-content "$file-temp" move "$file-temp" $file -Force
