Top Forums Shell Programming and Scripting Trouble reading content of file from a variable Post 302880740 by rbatte1 on Monday 23rd of December 2013 04:53:34 AM

So, are you saying that you have $a set as DML_FILE_NAME_ORIG1=$INF_COMRCLDATAMART_DML/ft_arnge_cred_risk_mtgt_fact.dml then?

This will not work. You are asking the shell to work with a file that isn't one. Which is the file you actually want to work with? I presume it's the one referred to by DML_FILE_NAME_ORIG1, i.e. $INF_COMRCLDATAMART_DML/ft_arnge_cred_risk_mtgt_fact.dml

This far down the chain of variables, the $ will just be a character. You need to get that interpreted before you call the cp command.


I would suggest that your logic is over complicated. Break it down to find a simpler way to refer to the file you need. If not, you will end up with a mess of:-
  • I want to use cp $a $b
  • $a refers to DML.....
  • $DML.... refers to $INF.... and a file.
It's just too messy.

Are the records in $AI_BIN/input.txt also variable names or variable assignments that you want to use? Can you share the format of that file so we can see what are trying to process.


Try to slim the code down to the minimal structure and just have a one record input file to your loop, then after pasting it into the thread along with the content of $AI_BIN/input.txt, can you run the script with ksh -x yourscript to illustrate where it is going. It might be obvious to you then, but if not I'm sure we can discuss it further.

script(1)						      General Commands Manual							 script(1)

NAME
script - Makes a transcript of terminal session SYNOPSIS
script [-a] [file] The script command makes a transcript of everything printed on your terminal. OPTIONS
Appends the transcript to file rather than writing it to file. OPERANDS
The name of an output file that will contain the transcript of the session. If this parameter is omitted, the file typescript is written. DESCRIPTION
The transcript is written to file, or appended to file if the -a option is given. If no file name is given, the transcript is saved in the file typescript. The script ends when the forked shell exits. This program is useful when you are using a CRT and want a hard-copy record of the dialog (for example, a technical writer might create an example of a working session this way). If you specify the -a option and the file does not exist, it is created. If you do not specify the -a option and the file exists, it is replaced. RESTRICTIONS
The script command requires a streams based terminal. In single user mode, streams may not be enabled. Under these circumstances, script will exit with no action. If you are the superuser and need to run this command in single user mode, use the following special instruc- tions. Enabling Streams If it is necessary to enable a streams environment in the single user mode, enter the command /sbin/init.d/streams. This command is avail- able to the superuser only. SEE ALSO
Commands: autopush(8), cat(1), echo(1), strsetup(8), tee(1) System Administration script(1)
