vim tabe split open more than 10 files from command line -

i want open multiple .cpp .h files in pair tabe , sp commands. suppose current workplace has a.h, a.cpp, b.h, b.cpp, ... z.h, z.cpp.

i tried following:

vim a.cpp -c 'sp a.h' -c 'tabe b.cpp' -c 'sp b.h' -c 'tabe c.cpp' -c 'sp c.h' -c 'tabe d.cpp' -c 'sp d.h' -c 'tabe e.cpp' -c 'sp e.h' -c 'tabe f.cpp' 

which work. however, number of -c commands limited 10. if want open more 12 files, fail.

vim a.cpp -c 'sp a.h' -c 'tabe b.cpp' -c 'sp b.h' -c 'tabe c.cpp' -c 'sp c.h' -c 'tabe d.cpp' -c 'sp d.h' -c 'tabe e.cpp' -c 'sp e.h' -c 'tabe f.cpp' -c 'sp f.h' ... 

will fail.

is there way make work?

you can use | separate command in vim. can combine of -c 1 command , pass -c

vim a.cpp -c 'sp a.h | tabe b.cpp | sp b.h | tabe c.cpp | ...'

assuming in folder cpp , header files run

vim -p *.cpp -c 'tabdo sp %<.h' 

to everything. -p tells vim open files in tabs. every cpp file in directory have 1 tab. after vim loaded run sp %<.h in each of tabs. where
%<.h original filename extension change .h. (%< filename without extension. take @ :help %<)

vim defaults having 10 tab pages. if need open more need increase tabpagemax value.

set tabpagemax=100 

take @ :help tabpagemax (if need many tab pages recommend learning how use buffers)
