How to handle looping to create file using powershell? - powershell

Question

I have INI file and I want to get specific section. The items in the section that I choose are 24 items. I want to use all the item to write in a file. I tried this, It works, but it looks like bad way to write 24 times to do the process. Is there any other way to do that more beautiful? The section of my INI file like this
Input ini:
[Code]
A1=12,34,56
A2=23,45,67
A3=34,56,78,9,10
...
A24=a1,b2,c3,d4,e5
Script:
Function F_ML
{
$FilePath = "C:\Users\File.ini"
$section = "Code"
$R_1 = "A1"
$R_2 = "A2"
$R_3 = "A3"
$R_4 = "A4"
$R_5 = "A5"
$R_6 = "A6"
$R_7 = "A7"
$R_8 = "A8"
$R_9 = "A9"
$R_10 = "A10"
$R_11 = "A11"
$R_12 = "A12"
$R_13 = "A13"
$R_14 = "A14"
$R_15 = "A15"
$R_16 = "A16"
$R_17 = "A17"
$R_18 = "A18"
$R_19 = "A19"
$R_20 = "A20"
$R_21 = "A21"
$R_22 = "A22"
$R_23 = "A23"
$R_24 = "A24"
$store = "C:\Users\"
$FilePath
$input_file = $FilePath
$ini_file = #{}
Get-Content $input_file | ForEach-Object {
$_.Trim()
} | Where-Object {
$_ -notmatch '^(;|$)'
} | ForEach-Object {
if ($_ -match '^\[.*\]$') {
$section = $_ -replace '\[|\]'
$ini_file[$section] = #{}
} else {
$key, $value = $_ -split '\s*=\s*', 2
$ini_file[$section][$key] = $value
}
}
#--------
$Path_Store = $store
#---------
$Get_1 = $ini_file.($section).($R_1)
$L_1 = $Get_1.Substring(0,3)
$Get_2 = $ini_file.($section).($R_2)
$L_2 = $Get_2.Substring(0,3)
$Get_3 = $ini_file.($section).($R_3)
$L_3 = $Get_3.Substring(0,3)
#---------
$Outer = ";********************"
$Header = ";*******************"
$ML = "12345"
$FB = ";Initial=1a2b"
#----------
$B_ID_1 = ";Build=" + $ML + "#" + "S" + $L_1 + "#" + "D" + $L_1
$CRM_1 = ";CRM=" + $R_1
$Output_1 = $Header, $B_ID_1, $FB, $CRM_1 , $Outer | Out-File $Path_Store\A1
$B_ID_2 = ";Build=" + $ML + "#" + "S" + $L_2 + "#" + "D" + $L_2
$CRM_2 = ";CRM=" + $R_2
$Output_2 = $Header, $B_ID_2, $FB, $CRM_2 , $Outer | Out-File $Path_Store\A2
$B_ID_3 = ";Build=" + $ML + "#" + "S" + $L_3 + "#" + "D" + $L_3
$CRM_3 = ";CRM=" + $R_3
$Output_3 = $Header, $B_ID_3, $FB, $CRM_3 , $Outer | Out-File $Path_Store\A3
#---------
}
$call = F_ML
My expectation, I can make this way shorter and the output is getting 24 output file.
Output Sample
Output File 1
;********************
;Build=12345#S12#D12
;Initial=1a2b
;CRM=A1
;********************
Output File 2
;********************
;Build=12345#S23#D23
;Initial=1a2b
;CRM=A2
;********************

Answer 1

Try below...
$IniContent = Get-Content -Path $IninPath
$IniContent | ForEach-Object -Process {
$Split = $_ -split '=';
$OutPutfilePath = "c:\temp\$($Split[0]).txt"
$first = ($Split[1] -split ',')[0]
$append = "#S{0}D{1}" -f $first,$first
# create a herestring to build the output
#"
;********************
;Build=$Ml$append
$FB
;CRM=$($Split[0])
;********************
"# | Out-File -Path $OutPutfilePath -Force
}

Answer 2

Use a ForEach to manipulate a string and Invoke the Expression.
1..24 | ForEach-Object { Invoke-Expression -Command (
'$R_{0} = "A{0}"' -f $_
)}
.
.
.
1..24 | ForEach-Object { Invoke-Expression -Command (
'$Get_{0} = $ini_file.($section).($R_{0}) `
$L_{0} = $Get_{0}.Substring(0,3)' -f $_
)}
.
.
.
1..24 | ForEach-Object { Invoke-Expression -Command (
'$B_ID_{0} = ";Build=" + $ML + "#" + "S" + $L_{0} + "#" + "D" + $L_{0}
$CRM_{0} = ";CRM=" + $R_{0}
$Output_{0} = $Header, $B_ID_{0}, $FB, $CRM_{0} , $Outer | Out-File $Path_Store\A{0}' -f $_
)}
{0} will be replaced by the value behind -f so it will be replaced Foreach number from 1 to 24...

Answer 3

Would this work?
All I did here was use your existing code to run everything in a loop from 1 to 24, removing the duplicated code. I reformatted it a little so it was a little easier for me to read.
Essentially, the variable $i will be a number from 1 to 24, while the variable $R will be "A" and whatever number is in $i (essentially A + $i)
Function F_ML
{
$section = "Code"
$store = "C:\Users\"
$input_file = "C:\Users\File.ini"
$ini_file = #{}
for ($i=1; $i -le 24; $i++)
{
$R = "A$($i)"
Get-Content $input_file |
ForEach-Object `
{
$_.Trim()
} |
Where-Object `
{
$_ -notmatch '^(;|$)'
} |
ForEach-Object `
{
if ($_ -match '^\[.*\]$')
{
$section = $_ -replace '\[|\]'
$ini_file[$section] = #{}
}
else
{
$key, $value = $_ -split '\s*=\s*', 2
$ini_file[$section][$key] = $value
}
}
#--------
$Path_Store = $store
#---------
$Get = $ini_file.($section).($R)
$L = $Get.Substring(0,3)
#---------
$Outer = ";********************"
$Header = ";*******************"
$ML = "12345"
$FB = ";Initial=1a2b"
#----------
$B_ID = ";Build=" + $ML + "#" + "S" + $L + "#" + "D" + $L
$CRM = ";CRM=" + $R
$Output = $Header, $B_ID, $FB, $CRM , $Outer | Out-File $Path_Store\$R
}
}
