UNIX for Dummies Questions & Answers

I have three question about find

1)regardless if it can "find" something or not, the "find" will return 0,how can we use "if" to judge not find or find?

for example
#find bin/ -name bla.c
1)find it will return 0
2) not found it will return 0

the question is how can I use "if" in the bash to judge it find or not

2)can we find in something specific directory(bin,/usr/bin)

eg:I want find the bla.c only in the "bin" and "/usr/bin"

3)can we find something not in some directory(bin,/usr/bin)

eg:I want find the bla.c not in the "bin" and "/usr/bin"

You need to be more specific on what you mean here. To find something or not something, just use grep


> 2)can we find in something specific directory(bin,/usr/bin)

Yes

> 3)can we find something not in some directory(bin,/usr/bin)

Again, you need to be more specific on what you mean here. To find something or not something, just use grep

1) You must be kidding... (ok - answer : Yes...)

2 and 3 are answered in the man pages...

It doesn't work this way. You can't just open up another thread with the same questions when you are not satisfied with the answers here in hoping to get other or better answers.
It would be helpful if you maybe answer to the statements being made or rephrase your questions.

look:

Code:

n12:/home/vbe $ find bin/ -name bla.c
n12:/home/vbe $                               # <- empty: nothing found
n12:/home/vbe $ find bin/ -name prn  
bin/prn                                             # found!

dont confuse return code (exit value...) and what the command returns (result of the search using find...)

Here is the case of return code that isnt 0:

Code:

aco $ find ./home/oracle/.dt/Desktop -name toto;echo $?
find: cannot open ./home/oracle/.dt/Desktop
