sprintf() , printf() may looking for. awk not support backreferences gawk's gensub(), or gsub() can provide backreferences.

backreferences storing strings matched. so, making use of awk's capability differentiate fields , field delimiters, using internal variables ofs,fs,ors etc way go.. eg

$ echo "test.txt" | sed 's/\(.*\).txt/\1.pdf/' test.pdf  $ echo "test.txt" | awk -f"." '{$nf="pdf"}1' ofs="." test.pdf

of course, simple example. idea.

unit testing - How to mock PreferenceManager in Android? -

i've written class using context , third party library , sharedpreferences preferencemanager . it's possible mock context , third party library can mocked using mocking framework, preferencemanager ? i have 2 methods: public void savestring(thirdpartyobject obj) { sharedpreferences apppreferences = preferencemanager.getdefaultsharedpreferences(mcontext); sharedpreferences.editor editor = apppreferences.edit(); editor.putstring(mcontext.getstring( r.string.preferences_string_name), obj.getstring()); editor.commit(); } and corresponding, loads preferences. it doesn't want mock instance of preferencemanager (which used in preferencefragment or preferenceactivity ). you want either: a mock sharedpreferences , in case can mock context#getsharedpreferences (which called preferencemanager#getdefaultsharedpreferences anyhow). you'll have make mock sharedpreferences.editor if preferences edited, above. know how moc...
