Shell Programming and Scripting

hi,

i have the below contents in a variable

Code:

echo $var
1 3 5 7 9 11 13 15 17 19 21 23 25 27 29 31 33 35 37 39 41 43 45 47 49 51 53 55 57 59 61 63 65 67 69 71 73 75 77 79 81 83 85 87 89 91 93 95 97 99 101 103 105 107 109 111 113 115 117 119 121

what i want to achieve is everytime i run a command i want to shift numbers to left deleting first number in the series...

that is i want to to retrieve first number in the variable everytime so i will be using below command

Code:

echo $var | awk -F' ' '{print $1}'

so when i do that i will retrieve 1 but next time when i execute same command i want to get 3 and next time 5 and so on.... so to do that i need to shift numbers to left no matter how many digits each number has...

any help is deeply appreciated :-)

Code:

$ var="1 3 5 7 9 11 13 15 17 19 21 23 ..."
$ set -- $var
$ shift
$ var=$@
$ echo $var
3 5 7 9 11 13 15 17 19 21 23 ...

You could maybe encapsulate it into a function for easier use.

.......

thanks scott,... above code works like a jem :-)
