Re: [PLUG] scripting help, variables in sed

The pithy ruminations from Michael Lazin on 
[[PLUG] scripting help, variables in sed] were:
=> My girlfriend has a large collection of scanned family photos many of which
=> are different photos with the same name.  We eliminated all duplicates with
=> fdupes, but she would like to put them all in one folder and give it to her
=> sisters on a cd.
=> 
=> I had a bit of free time this morning and tried to write a for loop to
=> accomplish this but I'm getting syntax errors and I'm kinda stuck.  Any
=> help would be appreciated.  Here is my code so far:
=> 
=>   #!/bin/bash
=> var=1
=> for i in *.jpg; do sed -i -e "s/"($i)"/"($var++)""($i)/" ; done


	i=1 ls -1 *.jpg |while read filename; do mv $filename ${i}_${filename}; i=$((i+1)) ; done

Substitute "ls -1" with "find", change the target of "mv" to include a
directory, etc.

For bonus points...eliminate the $i variable and use options in "ls"
(or "find") to preceed the target filename with the source file's inode
number, guaranteeing a unique number (for a given filesystem).

Or
	i=1 ls -1 |awk '{print "mv " $1 " " NR "_" $1}' | sh
