Create and write to .plist using terminal or bash script
I need to create a .plist file during post install and the only option I can use is a bash script. I need to create foo.plist in /Library/launchAgents
with a bash script and I used the following command:
cd /Library/launchAgents
touch foo.plist
now i need to write the content to this .plist file like:
".plist contents" >> foo.plist
Is there a command that can do this in the terminal?

Your question doesn't state very well what you have, or why you need to do it in bash
, but if you have to do it this way, you can do it like this:
#!/bin/bash
VERSION=2.12
cat > foo.plist <<EOF
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
<key>BuildAliasOf</key>
<string>ProEditor</string>
<key>BuildVersion</key>
<value>$VERSION</value>
</dict>
</plist>
EOF
So, you save this in a file named Buildplist
and then you do this to make it executable
chmod +x Buildplist
and then start it by typing the following:
./Buildplist
You can force it to write the plist file directly to /Library/launchAgents
by changing the second line to something like this:
cat > /Library/launchAgents/yourApp/yourApp.plist <<EOF
You can make it accept parameters too. So if you want to pass the Author as the first parameter, you can do it like this:
#!/bin/bash
VERSION=2.12
AUTHOR="$1"
cat > foo.plist <<EOF
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
<key>BuildAliasOf</key>
<string>ProEditor</string>
<key>BuildVersion</key>
<value>$VERSION</value>
<author>$AUTHOR</author>
</dict>
</plist>
EOF
and then run
./Buildplist "Freddy Frog"
transfer "Freddy Frog" as the author.
If you want to avoid overwriting any plist file that already exists, you can do it like this:
#!/bin/bash
PLISTFILE="/Library/launchAgents/yourApp/yourApp.plist"
# If plist already exists, do not overwrite, just exit quietly
[ -f "$PLISTFILE" ] && exit
cat > "$PLISTFILE" <<EOF
...
...
EOF
I put the name of the plist file in a variable to make it easier to maintain and not have to type it twice.

PlistBuddy is what you want.
/usr/libexec/PlistBuddy Info.plist
File Doesn't Exist, Will Create: Info.plist
Then add an entry to a file like this,
/usr/libexec/PlistBuddy -c 'add CFBundleIdenfier string com.tencent.myapp' Info.plist
By the way, man plist
it man plutil
may be useful to you.
