To extract the name of the file the quick way is to use substr and rindex commands to strip the path from filename as shown below.
#!/usr/bin/perl my $path='/path/to/search/filename'; my $fname= substr($path, rindex($path,"/")+1, length($path)-rindex($path,"/")-1); print "$fnamen";
If you have the luxury of using Perl Packages, then use following solution which is very clean.
#!/usr/bin/perl use File::Basename; my $path='/path/to/search/filename'; my $fname = basename($path); print "$fnamen";
Bash expands a list of strings separated by commas with in braces to a list of strings separated by spaces. For example
[unixite@theunixtips:~/> echo 111-{aa,bb,cc}+{xx,yy,zz}-222
111-aa+xx-222 111-aa+yy-222 111-aa+zz-222 111-bb+xx-222 111-bb+yy-222 111-bb+zz-222 111-cc+xx-222 111-cc+yy-222 111-cc+zz-222
unixite@theunixtips:~/>
There should not be any space between suffix/prefix and the start/end bracket. Otherwise it is considered as a separate list. Now coming to a real world example where you can make use of this.
mv process.log{,.old} #This will move process.log to process.log.old
mv process.log.{old,oldest} #This will move process.log.old to process.log.oldest
