Homework & Coursework Questions

Use and complete the template provided. The entire template must be completed. If you don't, your post may be deleted!

1. The problem statement, all variables and given/known data:

list is long form all those files in your home directory that have read write and execute permissions for you, and whose name contains the string "txt"

2. Relevant commands, code, scripts, algorithms:
ls
find


3. The attempts at a solution (include all code and scripts):
ls -l would tell me the permissions
but find . -type perm 777 would give me files that have read write execute permissions
However , i feel like i should pipe it because i need a long form of those files


4. Complete Name of School (University), City (State), Country, Name of Professor, and Course Number (Link to Course):
Toronto, Ryerson , Woit, cps393

Note: Without school/professor/course information, you will be banned if you post here! You must complete the entire template (not just parts of it).

There should be nothing wrong with a pipe, but you would need xargs to make ls read from stdin - though here is an example how to do it without a pipe:

Code:

find . -perm 777 -name "*txt*" -exec ls -l {} \;

I am not sure if 777 is the right way, since your user would be able to rwx it, no matter if he is owner or in the group, as all (others) can rwx it. Since it is your home directory being mentioned you should be the user that has rwx on it. So to be more exact, you might take

Code:

find . -perm u=rwx -name "*txt*" -exec ls -l {} \;

as this just defines permissions for the user/owner of the file(s).

And if it is really only files you should list, ie. no directories, I would suggest:

Code:

find . -type f -perm u=rwx -name "*txt*" -exec ls -l {} \;

hi thank you for the help, would this work out the same too
ls -l | find . -name "*txt*" - perm 700

forget the above, it says list in short form ( just the file names) , so the command
find . -perm 777 -name "*txt*"
would allow me to list in short form ( namely just the file names) ?

This should find all files which match the criteria:

Code:

find . -type f -name '*.txt' \( -perm -0700 -o -perm -0070 -o -perm -0007 \) -exec ls -ald {} \;
