I was trying a shell script. I was unable to store file contents to a variable in the script. I have tried the below but unable to do it.
Input = `cat /path/op.diary`
Input = $(<op.diary)
I am using ksh shell. I want to store the 'op.diary' file contents to the variable 'Input' and i want to use some other commands later on the variable 'Input'.
Not sure about your complete requirement but storing whole file's content into a single variable doesn't seems to be a good method, in spite of that you could read a file line by line by using while loop or you could use awk, sed to accomplish your requirements, if you have any queries please do let us know complete requirement with sample Input_file and expected output, hope this helps.
Thanks,

This User Gave Thanks to RavinderSingh13 For This Post:
After storing the file contents to a variable , I want to use grep command to remove some of the records in field 2 and then i want to append some other file to the resulting file.
When i am asking the user to enter the file manually and read the file with the
Code:
read
command, i am able to do it but when i am trying the script to read itself,can not able to do.
Please let me know your thoughts on this.
Thanks in advance.

One more thing i would like you to know that i did not try using awk or sed as i do not know how to use them for this purpose.
Thanks for your reply. I just want to make the shell script to read the file on its own instead of manually entering input. Below is how my sample file looks like. I want to store it in a variable say 'Input'.
You haven't shown the expected output or your aim for writing the script(you have mentioned same thing of storing the Input_file's line into a variable which you told into very first post.). Putting a very wild guess like you wanted to print field 2 of each line, following may help you in same the.
am24, do you see a syntax error when you use the commands in your first post or what does "unable to do it" mean?
When you asign a value to a variable there are no spaces allowed around the equal sign, no matter where the content of the variable came from.
At least this should work unless you hit some size limit:
In the below bash I am trying to read each file from a specific directory into a variable REF or VAL. Then use those variables in an awk to compare each matching file from REF and VAL.
