Full Discussion: Need help with 2 similar commands with different outputs
Top Forums UNIX for Dummies Questions & Answers Need help with 2 similar commands with different outputs Post 302655529 by jawsnnn on Wednesday 13th of June 2012 09:40:12 AM

I guess (and it is just a guess, since I know next to nothing about how shell works) is that
1. Since the variable $FILE may refer to more than one files, grep is showing you the exact filename which matches content.
2. The variable TIME is not quoted in the grep command. Doesn't it show you a "no file or directory found" message? What is the output of:

Code:
TIME="Time: 20120611";FILE=file.log; grep "$TIME" $FILE

If it does not show you the file name in output, then my guess is that the part after "Time:" of the TIME variable is being treated as one of the search files and hence the output tells you the name of the file in which the data is found (as is the norm for multiple file grep).
