Question

I want a script that I run thusly:

logphone Foo Bar Tar:I Baz:D

Which actually runs

adb -d logcat dalvikvm:I ActivityManager:W AndroidRuntime:W Foo:* Bar:* Tar:I Baz:D *:S

How do I do this with any number of parameters? Note that the order somewhat matters (Foo, Bar, etc. can’t be at the end). Bash if it matters.

I can break the steps down to

1. For any number of command line arguments…
2. Check each argument for a colon (:)
3. If there’s no colon add :*, otherwise leave it alone
4. Inject it into the command line adb logcat dal…time:W __INJECTED_ARGS__ *:S

Answer 1

Try the following bash code. Don’t forget the shebang (if not /bin/bash) and chmod +x script.sh :

#!/bin/bash

for arg; do
    if [[ "$arg" == *:* ]]; then
        args="$args $arg "
    else
        args="$args $arg:* "
    fi
done

exec adb -d logcat dalvikvm:I ActivityManager:W AndroidRuntime:W ${args[@]} *:S

If you have a recent bash (see it with bash -version), I can improve it a bit.
