Compare Files Remotely with Diff

For example, compare ~/.vimrc at different hosts:

ssh bvt@10.0.2.74 "cat /home/bvt/.vimrc" | diff -y --suppress-common-lines - .vimrc

where -y is abbr. of "--side-by-side".

Compare Files in Two Directories

Usually we use the following command to compare source files in two directories:

Find out which files are different

┌─[lichao@lichao480] - [~/docs/erlang/processquest-1.0.0/apps] └─[$] diff -rq sockserv-1.0.0/src sockserv-1.0.1/src Files sockserv-1.0.0/src/sockserv_serv.erl and sockserv-1.0.1/src/sockserv_serv.erl differ

then use vimdiff to show detailed differences between these files.

-r means "recursively", -q means only report different files.

Print out differences of files directly

┌─[lichao@lichao480] - [~/docs/erlang/processquest-1.0.0/apps] - [1672] └─[$] diff -y --suppress-common-lines sockserv-1.0.0/src sockserv-1.0.1/src diff -y --suppress-common-lines sockserv-1.0.0/src/sockserv_serv.erl sockserv-1.0.1/src/sockserv_serv.erl > gen_tcp:close(S#state.socket), terminate(normal, #state{socket=S}) -> | terminate(normal, _State) -> gen_tcp:close(S); | ok;
