How can I append the name of a file to end of each line in that file?
Question
I need to do the following for hundreds of files: Append the name of the file (which may contain spaces) to the end of each line in the file.
It seems to me there should be some way to do this:
sed -e 's/$/FILENAME/' *
where FILENAME
represents the name of the current file. Is there a sed variable representing the current filename? Or does anyone have a different solution using bash, awk, etc.?
Solution
I'm sure there are other ways to do it, I'd use perl:
perl -p -i -e 's/$/$ARGV/;' *
OTHER TIPS
Some versions of sed support the "--in-place" argument so you can condense Tyler's solution to
for i in * ; do
sed -e "s/\$/$i/" --in-place "$i"
done
You could do it with a bash script
for i in *
do
sed -e "s/\$/$i/" "$i"
done
One-liner version:
for i in * ; do sed -e "s/\$/$i/" "$i" ; done
Edit: If you want to replace the contents of the file with the new, name-appended lines, do this:
TFILE=`mktemp`
for i in *
do
sed -e "s/\$/$i/" "$i" > $TFILE
cp -f $TFILE "$i"
done
rm -f $TFILE
awk '{print $0,FILENAME}' > tmpfile
In BASH, I'd do something to the effect of:
for f in *; do echo $f >> $f; done
More or less how Tyler suggested, just with some modifications to allow for spaces in the name. I was hoping for a one-liner though...
(
OLDIFS=$IFS
IFS=$'\n'
for f in *
do
IFS=OLDIFS
sed -e "s/\$/$f/" $f > tmpfile
mv tmpfile $f
IFS=$'\n'
done
)
This might work for you:
printf "%s\n" * | sed 's/.*/sed -i "s|$| &|" &/' | bash
