• Check what group user belongs to?

• grep on all the files in a directory

Use one of the greps (grep, egrep, fgrep). You want to use the -r "recursive" option to search a directory and all files included within it.

grep -r -i ONOCR /usr/include

[nsl@nsl]$ grep -r -i ONOCR /usr/include
/usr/include/asm/termbits.h:#define ONOCR       0000020
/usr/include/linux/cdk.h:#define        FO_ONOCR        0x8
/usr/include/linux/tty.h:#define O_ONOCR(tty)   _O_FLAG((tty),ONOCR)
/usr/include/bits/termios.h:#define ONOCR       0000020

The '-i' means ignore case. So if you only wanted it in all capitals you would not use it. When used it will find any combination of upper and lower case.
