Here is what I have:
Code:
#!/bin/bash

file=BuildManifest.xml
read num < "$file"
printf "%d\n" "versionCode=$(( $versionCode + 1 ))" > "$file"


but I keep getting this error in Terminal
Code:
build.sh: line 5: printf: versionCode=1: invalid number

Is the file in Windows/DOS format with a CR at the end of the line? If so:
Code:
CR=$(printf "\r")
printf "%d\n" "versionCode=$(( ${versionCode%"$CR"} + 1 ))" > "$file"

That differs pretty much from your initial request, but here we go: first you'll have to pick the number out between the quotes
(following sed command deletes all but digits):

Code:
read num < "$file"
num=$(echo $num | sed 's/[^0-9]//g')
printf "Versioncode=\"%d\"\n" "$(( $num + 1 ))" > "$file"

Hi Guys, It changed the number. The only problem and I really apologize for not offering more information at the start is it prints the new # and thats it. I have a file with 10 lines of xml code and just wanted to change the version # and it wipes the file and just prints the

VersionCode="2" or whatever number it is at that time

The number changing is perfect Smilie just need it to only change that. Any suggestions?

Can you post your current code which is working (apart from overwriting the input file and only printing VersionCode="2" in it)?
Can you post that 10 lines of xml code (the file that needs to be modified)?

Code:
#!/bin/bash

file=BuildManifest.xml
grep versionCode $file > vercheck.txt
vercheck=vercheck.txt
increase=increase.txt
read num < "$vercheck"
num=$(echo $num | sed 's/[^0-9]//g')
printf "versionCode=\"%d\"\n" "$(( $num + 1 ))" > "$increase"
sed -i 's/$vercheck/$increase/g' $file

Some of the XML:

Code:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:build="http://builds.builds.com"
      package="build"
      versionCode="1"
      versionName="1.0">
    <uses-permission name="build.permission.SEND" />
    <uses-permission name="build.permission.INTERNET" />
    <uses-permission name="build.permission.RECEIVE" />
    <uses-permission name="build.permission.READ_STATE" />

If I got you right, you only want to increase the versioncode number in the xml file, right?
If yes, try this:

If it works, then we can talk about unnecessary parts of the script...
