How to Use Chaining Translation in Unix -


I want to translate the word "abcd" to the upper "ABCD" using the tru command if the "ABCD" Example 1234 for example

I want to combine two translations together (using lower case in upper case, then upper case up to 1234) and piping the final output more.

I'm not able to chain the second part.

echo "abcd" | | Tr '[: lower:]' '[: upper:]' & gt; File 1

Here I'm not sure how to add another translation into a single command.

You can not do this in a single tr command; You can do this in a pipeline: 

  "ABCD" echo. Tr '[: less:]' '[: upper:]' | Note that your  [: less:]  and  [: upper:]  notation will translate more than  abcd  to  aBCD  in comparison with. If you want to expand the mapping of the digits then map  A-I  to  1-9 , this is possible; What are the maps for  0 ?  
 If you want to do this in a single command, you can write:  
  echo "abcdABCD" | Tr 'abcdABCD' '12341234' or   
 Or, a little abridged:  $ echo 'abecedenarian-DIABOLICALISM' | Tr 'a-dA-D' '1-41-4' 12e3e4en1ri1n-4I12OLI31LISM $

I was trying to use the program to use mifrewan on 4 node clusters. Distributing node 0 data in nodes 1, 2 and 3. In the program, from '90 'to variable values ​​of' dior 'to be calculated. Therefore the node is distributing data and collecting results in an omitted fashion (for different values ​​of var 'dir') when do {*******} Whereas (dir Loop is given, Mippun is hanging, and no output is found. But when I comment on two {*******} (dir The loop output is obtained for the initial value of variable dir dir = -90 ), and that output is correct. The problem occurs when the loop is given. Can anyone help me in solving this problem. #include "mpi.h" int main (int argc, char * argv []) Float dir = -90; Int rank, nanoprakash; MPI_Status status; MPI_Init (& amp; argc, & argv); MPI_Comm_rank (MPI_COMM_WORLD, & amp; Rank); MPI_Comm_size (MPI_COMM_WORLD, & amp; numprocs); If (rank == 0) {/ / data to begin / / (dest = 1; dest ...

python - Apply coupon to a customer's subscription based on non-stripe related actions on the site -

I can not find anything in the source about using coupons after subscribing to a user's plan. Is it possible to use a coupon to credit a user's membership after initial subscription? If not, what is the best option? Specifically, I want to give a user 100% coupon for that month, when they take 5 [site specific actions]. This is possible, but may not be the best idea. Coupons are currently applied to the stripe, then apply again at the customer level and each client can have a single coupon. So if you are already offering discounts to the coupon, then the customer who is currently in the present will also give up. It also means that if you are using a recently-added multiple subscription capacity, then all of the user's subscription will be ready for the month. Coupons can be set to "Once", only once (as the only name) can be used by any customer, so if this credit can earn more than once, You will have to maintain a 100% discount coupon continuousl...
