I need to insert the following single line into an existing text file on many computers. Therefore, I need to automate this in a batch file.

Line to add:

<.add key="StudentAccountPaymentRunEnvironment" value="PRODUCTION"/>

The Destination for this string is in to a file called: O2-config.txt and within the O2-config.txt file, I need to insert the line shown above, just after the line shown below:

<.add key="TuitionPaymentRunEnvironment" value="PRODUCTION"/.>

So the final result will be:

Existing

<.add key="TuitionPaymentRunEnvironment" value="PRODUCTION"/> 

New

<.add key="StudentAccountPaymentRunEnvironment" value="PRODUCTION"/>

There are many lines of text preceding and following these two lines. Please advise. I searched and found solutions for linux, but not for a Windows/Command Prompt. I want to put this solution in a .bat file that can execute with Windows Group Policy.

Windows 10 comes with PowerShell, so you could use:

## Q:\Test\2018\12\07\SO_53661614.ps1
$Ins = [RegEx]::escape('<.add key="TuitionPaymentRunEnvironment" value="PRODUCTION"/>')
$New = [RegEx]::escape('<.add key="StudentAccountPaymentRunEnvironment" value="PRODUCTION"/>')
(Get-Content .\yourfile.txt) -replace $Ins,($Ins+"`n"+$new)|Set-Content .\yourfile.txt

Wrapping this in a batch :

:: Q:\Test\2018\12\07\SO_53661614.cmd
Set "Ins=<.add key="TuitionPaymentRunEnvironment" value="PRODUCTION"/>"
Set "New=<.add key="StudentAccountPaymentRunEnvironment" value="PRODUCTION"/>"
Powershell -Nop -C "(Get-Content .\yourfile.txt).replace($ENV:Ins,$ENV:Ins+\"`n\"+$ENV:New)|Set-Content .\yourfile.txt"

How do I add lines in a text file in a specific location using MATLAB , For example, assume this is the text file I am reading into MATLAB I want to add 'New sample line' right above the 'Interested location' so that my resulting This function I created to insert a given string into another given string at the lines​  To do that, we store the text to be inserted into a variable named strInsert, then simply combine the values of strLeft, strInsert, and strRight (plus a carriage return-linefeed tacked on to the end). That’s what we do here: strInsert = “This is inserted text”. strText = strLeft & strInsert & strRight.

You can get a Windows port of sed from this site.

Using that, you can execute this command:

sed -i "s/<.add key=.TuitionPaymentRunEnvironment. value=.PRODUCTION.\/>/&\n<.add key=\"StudentAccountPaymentRunEnvironment\" value=\"PRODUCTION\"\/>/" somefile.txt

And after that, the line-endings need to be repaired:

sed -i ":a;N;$!ba;s/\n/\r\n/g" somefile.txt

Note that I'm assuming there is only one instance of that text in your file.

For a solution that only modifies the first match of that string, you can put this into a batch file:

set MATCH=.add key=.TuitionPaymentRunEnvironment. value=.PRODUCTION.
sed "0,/%MATCH%/ {s/%MATCH%\/>/&\n<.add key=\"StudentAccountPaymentRunEnvironment\" value=\"PRODUCTION\"\/>/}" somefile.txt > temp.txt
sed ":a;N;$!ba;s/\n/\r\n/g" temp.txt > somefile.txt
del temp.txt

The following code example can be used in a document-level customization. Dim rng As Word.Range = Me.Range(Start:=0, End:=0) rng.Text = " New Text " object start = 0; object end = 0; Word.Range rng = this.Range(ref start, ref end); rng.Text = "New Text"; The following code example can be used in a VSTO Add-in.

How to insert text after a certain string in a file?, Append line after match. sed '/\[option\]/a Hello World' input. Insert line before match. sed '/\[option\]/i Hello World' input. Additionally you can take backup and  One way is to load the file into an ArrayList, with each item representing a line, then you can insert your text in the desired location using the ArrayList.Insert function, then use the StreamWriter to rewrite the file to disk from the array with each item written on a separate line. The code below shows how to do this task:

Java SE 8 for Programmers, Use \\ to insert a \ in a string literal. 15.4. Sequential-Access. Text. Files. Next, we create and manipulate sequential-access files in which A Formatter object can output to various locations, such as to a command window or to a file, If an existing file is opened, its contents are truncated—all the data in the file is discarded. It inserts New Text one line below each line that contains SearchPattern. To add two lines, you can use a \ and enter a newline while typing New Text. sed -i '/pattern/a \ line1 \ line2' inputfile

Comments
  • You may solve your problem using the same method described at this answer
  • Your Existing line once has a dot near the end and once NOT?
  • I don't think the reformatting helps in all areas. The existing and new headings don't make it clear that the new line is to be appended after the existing one. The "final result" (per the text) should show the two lines together, as intended.
