How can I search a wild card name in all subfolders? What would be the equivalent of DOS command: dir *pattern* /s in *nix?

You can use find. If, for example, you wanted to find all files and directories that had abcd in the filename, you could run:

find . -name '*abcd*'

Zsh:

ls -ld -- **/*abcd*

Ksh93:

set -o globstar # put this line in your ~/.kshrc
ls -ld -- **/*abcd*

Bash ≥4:

shopt -s globstar # put this line in your ~/.bashrc
ls -ld -- **/*abcd*

Yash:

set -o extendedglob # put this line in your ~/.yashrc
ls -ld -- **/*abcd*

tcsh:

set globstar
ls -ld -- **/*abcd*

fish:

ls -ld -- **abcd*

(beware some of those shells will follow symlinks when descending the directory tree; some of those that don't like zsh, yash or tcsh have ***/*abcd* to do it).

Portable (except to very old systems; OpenBSD took a long time but finally supports exec … + since 5.1):

find . -name '*abcd*' -exec ls -ld +

Not POSIX but works on *BSD, Linux, Cygwin, BusyBox:

find . -name '*abcd*' -print0 | xargs -0 ls -ld

Note that except in some BSDs, if no matching file is found, ls -ld will be run without arguments, so will list .. With some xargs implementations, you can use the -r option to work around that.

Not mentioned in the other answers is

ls -R1 | grep pattern

ls arguments used:

-R, --recursive
 list subdirectories recursively
-1 list one file per line
