Shell Programming and Scripting

Hi all

I want to use the filename passed into a shell script within the shell it self. The file will be passed as shown below

Code:

./myScript < myFile.file

i tried $1 but i think since myFile is not passed as a command line arg its not saving the file name in $1

any help is appreciated.

Can you call it like this?:

Code:

./myScript myFile.file < myFile.file

At least you will have it in $1

thankx for the reply

Well i can but its against the policy of my workplace. I would prefer if there was a simpler way of getting the filename in the way that i am calling the script

The filename is never "passed into the script". By the time your script is running, all the redirection has already happened, it never gets told a thing about it. You're trying to go backwards from a file descriptor to a filename, difficult to impossible in a shell.

What's the filename needed for? Maybe there's another way to accomplish what you want without it.

well basically im passing it to

Code:

awk

to generate a report. But before doing that i want to enter into a Log file the name of the file being processed

eg: Processing file <FILENAME>
...
...

i also need to use it within awk to print a few lines eg

Code:

{"head -n "FNR" <FILENAME> | tail -n 1"|getline temp } print ""temp"">> "Log"

If file name and location is fixed, then store it in variable and pass the variable to script.
Use variable in main script whenever u want using $variable.
