Rename Files 101

[migueljr3]

Greetings,

I would like to update one of our devices on our MRTG station as the name has changed, but would like to keep
all the data.

How do I rename all files with "mor1":
Such as:

map-mor1-rtr1_se0_0.1-month.png
map-mor1-rtr1_se0_0-week.png

To "mor161"

map-mor161-rtr1_se0_0.1-month.png
map-mor161-rtr1_se0_0-week.png

Please help with a quick shell script of some sort.

You could try the 'rename' command - just check out the manual page, it's quite a simple command provided you know regex.

I dunno but can "mv" be made to do this ?

How many files are there? If there are only a few, just use the mv command on each file, mv map-mor1-rtr1_se0_0.1-month.png map-mor161-rtr1_se0_0.1-month.png. If there are a lot of files, you may want to write a script to run through and change every occurrance.

Simplist is still:

rename s/map-mor1/map-mor161/ map-mor*.png

Miguel,
You can use the script above...

Replace each occurance of exp1 with mor1 and each occurance of exp2 with mor161 or whatever you like. I did test the script with the expression in the middle of the filename (I used it to changed 1000 or so .txt files to .html) I had to use the widcard before and after the expression so don't move them.

Thank you so much! How can run this script so I can add variables such as:

root@cheese#./renamer exp1 exp2


This is not working (bare with me, script newbie)

echo "Creating list of files that match your search query"
locate *$1* >> fileslist.txt
echo "Query complete. The list of files is saved as fileslist.txt"
echo
echo "Changing filenames....."
for FILE in *$1*; do
mv $FILE `echo $FILE | sed 's/$1/$2/'`
