trying to add a date stamp to the name of a file with sed. can't seem to comment out the date command so that sed does not only see it as a literal text string
this is what I'm trying
Code:
ls file.txt | sed 's/file.txt/file\/`date`\/.txt/g'
For standard shells, command substitutions are not performed inside single-quoted strings. And, if they were, the sed substitute command you're using would produce output similar to:
Code:
file/Thu Apr 6 12:06:36 PDT 2017/.txt
not:
Code:
file20170406.txt
Why are you performing a global substitution when there can never be more than one match?
What are you trying to accomplish? Using ls and sed won't rename a file. If you want to rename files, there are much more efficient ways of coming up with the new names without invoking external utilities (other than date and mv).
If you're not trying to rename files, what is the purpose of this exercise?

Hi
I use "touch -t xxxxxxxx" command to set date/time stamp of a file. My requirement is to read the date/time stamp of a file and apply it to another file.
Is there anyway to do it simple instead of manually taking date/stamp of first file?
