Shell Programming and Scripting

HI

I need help on developing 2 scripts as mentioned below.

One way process ->

We can get files of 01, 02, 07 record types (Here we need to keep a filter to read the first 2 characters in the file and if they are equal to 01 or 02 we need to do the below process and if its 07 we need to send the file as it is to a folder)

Scenario - 01:
In the file we received it would have only a single line with 300 bytes length, example below,

Code:

01NCX004HTXW000005241 DIEBOLD DECAL       5                                 Y0115131048OPBTicket:7550420   Status:IMPRESORA PROVEEDOR

01 - first field indicates record type
NCX004HTXW - second field
000005241 - third field - so here we want to make this 10 characters data to 30 characters just adding 20 spaces to this third field.

Code:

01NCX004HTXW000005241                     DIEBOLD DECAL       5                                 Y0115131048OPBTicket:7550420   Status:IMPRESORA PROVEEDOR

When we add 20 spaces to the 3rd field the length of record becomes 320 bytes , so we need to trim last 20 characters to make length to 300 bytes.

Response process:

From our backend we may get record types like 11,17,E1,E2,12,13,14 ((Here we need to keep a filter to read the first 2 characters in the file and if they are equal to 11,17,E1,E2 we need to do the below process and if its 12,13,14 we need to send the file as it is to a folder)

Scenario - 11 :

In the file we received it would have only a single line with 600 bytes length, example below, file attached (00567538.001)

Code:

11NCX006QHL7000005241                                                   OPBDIEBOLD DECAL       5             061013101906101310190611131119                                                                       FL0005675338600700338                         OP230

11 - first field indicates record type
NCX006QHL7 - second field
000005241 - third field - so here we want change 30 characters data to 10 characters ( by trimming the data which is coming from position 23 - 43 bytes (total 20 characters))

Code:

11NCX006QHL7000005241                               OPBDIEBOLD DECAL       5             061013101906101310190611131119                                                                       FL0005675338600700338                         OP230

When we trim 20 spaces to the 3rd field the length of record becomes 580 bytes , so we need to add 20 spaces to the end of the file to make length to 600 bytes.

Moderator's Comments:

Please use CODE tags; without them it is impossible to determine the number of spaces between fields and at the end of a line.

So, what have you tried so far.................?

I will continue to delete any contributions (2 so far) until the user has answered the question asked in post #2. Thanks.
