Using > to output a file in shell, linux show ": Operation not permitted"

[CoolEagle]

cat shelltest
awk -f ./LCD.awk ./time2Collection.txt > abc.txt

see above, just one command in shell. when running it , linux shows ": Operation not permitted". If cut down "> abc.txt", It's OK.

but strange thing is , when i ran this awk command directly in linux command line, it's ok. I login in linux with Root.

how to solve it?

thank you.

It is likely that you do not have execute+write permission on the directory you are in. Try >/tmp/abc.txt instead.

Thank you very much. It works.
but it's strange to me!

if I run awk -f LCD.awk time2Collection.txt > abc.txt in current folder, It's OK and abc.txt is created correctly. but I run shell which has same command in this folder, it will show "Operation not permitted"

Do you konw how to fix it. I want to let abc.txt creat in currect folder.
thank you

Check the permissions of the shell script.
