Hii people uhhuhuhu i need use the while command in a command line in a c shell and bash exemple ssh 172.30.30.30 -l user set a=1; while ( $a <= 10 ); echo $a. set a=`expr #a + 1`; end this is wrong,, but anyone know how can i get ???

I don't have access to a bash shell at the moment, but was able to get the below to work (without the ssh). You may not need the " either, but I like to use them around the command. ssh 172.30.30.30 -l user "a=1; while [ $a -le 10 ]; do echo $a; a=`expr $a + 1`; done" Be sure to come back and let us know if our suggestions helped!

nothing happended... this string a=1; while [ $a -le 10 ]; do echo $a; a=`expr $a + 1`; done its ok,,, but the problem is i do it in another computer with csh ,, i try many possibilities,,, but its almost impossible...

It's a lot easier if you use the arithmetic expressions and evaluation native to bash: for ((a=1;a<=10;a++));do echo $a; done

Wait a minute! - you're running in a csh environment on the remote machine? In the csh manual it says you have to have the 'while' and 'end' statements on a line on their own: ssh 172.30.30.30 -l user 'set a=1 while ( $a <= 10 ) ... end'

i have been tried it too,,, but the command "while" execute only 1 time the loop, and it have to be execute 10 times... yeah,,, i am running csh in a remote machine huhuhuhuhu it is almost impossible....

Yes - I tried this myself and everything works fine with bash but it does not work with csh. Not much does. ;-)
