How do I read a file field-by-field under UNIX / Linux / BSD Bash shell? My sample input data file is as follows:
For each line I need to construct and execute a shell command as follows:
/path/to/deviceMaker --context=$1 -m $permissions $device2 $deviceType $major $minor
How do convert tabs to spaces in a file using a bash shell?
I want to run a Unix command 100 times using a for loop from 1 to 100. Can you tell me how to take a block of numbers in a loop under KSH or BASH shell?
If var is defined AND NOT EMPTY, use var, otherwise set a default variable under Bash. For e.g. my script needs a parameter for output variable. It can be text or html. I set it as follows in my script
output=$1 # either text or html
However, sometime user forget to pass the parameter to my shell script and my enter logic fails. So how do I set default value to text, if no parameter passed?
