Started to learn some shell scripting. I have a perl script that runs on one file. How would I write a shell script to run the perl script a bunch of times on all files with keyword "filename" in it?
So in English,
for /filename/ in filenames
perl myscript.pl completefilename
Thanks.
find . -name "filename*" -exec perl myscript.pl '{}' \;
for i in $(\ls -d filenames)
do
perl myscript.pl $i
done
The backslash in front of the 'ls' command is to temporarily disable any aliases.
HTH
find . -path "\*filename\*" -exec perl myscript.pl {} \;
edit: escaped stars, didn't want the markup here
In bash:
files=`ls -1 *`
for $file in $files;
do
perl myscript.pl $file;
done
One liner:
$ for file in filename1 filename2 filename3; do perl myscript $file; done
Instead of the space separated list of filenames you can also use wildcards, for instance:
$ for file in *.txt *.csv; do perl myscript $file; done
And if you have spaces in your filenames, use the old standby
find . -maxdepth 1 -print0 | xargs -0 perl myscript.pl
FILES="keyword"
for f in "$FILES" do perl myscript.pl $f done
I personally use the zsh shell, which gives you a very nice way to run a command recursively on a set of subdirectories. It also allows you to change the suffix of the file, which is handly when using lame to create MP3 files of .wav files:
for i in **/*.wav; lame $i $i:r.mp3
You can also pipe the output of one command to another, which I something I use frequently when I'm downloading a number of bittorrent files and want to see the percentage that each download has completed:
for i in **/*.txt; grep -H percent $i | tail -1
