View 14 Replies View RelatedGeneral :: Shell - Rename A File From Something Without Spaces To Something Containing Spaces?
Jan 26, 2010Is it possible, in Linux, to rename a file from something without spaces to something containing spaces? I know I can create directories and files with spaces by doing:
mkdir "new dir" and:
touch "new file.txt"
I want to rename files from:
imgp0882.jpg to something like:
20091231 1243 some topic.jpg
And how would it look in a shell script that uses parameters like:
for i in *.jpg do
rename "$i" "$somepath/$mydate $mytime $mytopic$extension"
?
I'm new to Linux (using PCLinuxOS 2009.2), coming from Windows, and I've written myself a little shell script to download files from my camera and then automatically rename them according to a date-and-topic pattern. As you can guess by now, I'm stuck on the bit about renaming. If you want to see my script, here's a copy. I'm not using jhead for this renaming because that only works with JPEG files but I want a single solution for any media format including videos.

Feb 25, 2011Code:
#!/bin/bash
VARR=`cat /proc/asound/cards | grep HDMI | cut -c 1-2`
VARX="defaults.ctl.card $VARR"
VARY="defaults.pcm.card $VARR"
FILE1="alsa"
FILE2="alsa.new"
echo $VARX
echo $VARY
sed "s/defaults.ctl.card*/'$VARX'/g" $FILE1 > $FILE2
This is what I have right now. Well, I thought I knew sed, and apparently I don't... I tried writing this for someone else, and this has given me trouble, so since the user pretty much figured it out on his own, here it goes.
Say VARR=1, so VARX and VARY contain the above text, appended by 1.
What I am trying to do is replace the text "defaults.ctl.card 0" by VARX and "defaults.pcm.card 0" by VARY. The contents of FILE1 is the file being used to search for both text fields, and FILE2 is the output file. I tried using single quotes, double quotes, and a mixture of both, and no go whatsoever. So my question... What is the proper way of searching for text within a file and replacing with a variable?

General :: Find And Replace Text From Many Files In A Dir?
Jul 8, 2010I have a many directories each with about 20 html files inside. All the files have .html ext. What I'm hoping is possible is from command line to find some text in each one and replace it with some other text.
Basically what I want to replace is;
/awstats/
with
awstats/
I can do this easily with dreamweaver or some other application but because I have 960 pages total to do I'm hoping to do it this way.
