I am trying to do a for loop, but Cygwin does not understand the {$var} syntax.
My command:
for f in 'svn ls repo_path'; path/{$f}trunk/path; done
Error svn: E170000: URL path/%7Bvar%7Dtrunk/path doesn't exist
The string should come out to be: path/var/trunk/path
How can I make the variable + string concatenation work?

The syntax is ${f}, not {$f}.
If you really want path/var/trunk/path, you can simply use path/$f/trunk/path. This works whether $f end with a slash or not. Bash doesn't mind a double slash.
Also, be careful with parsing the output of ls.
Actually, now I am having this problem: for f in 'svn ls repo_path'; path/${f}trunk/path; done
Comes out as: path/var/%0Dtrunk/path
%0D is a carriage return character. A newline in Windows is \r\n, not the expected \n.
Try setting
IFS=$' \t\r\n'
before the for loop.

Wow... Thank you for pointing that out. Been a long day! Would upvote you if I could. – user1776193 – 2013-03-26T02:53:53.800

Nevermind, I guess I can't comment because I don't have enough reputation. Sorry for this hard to read question: – user1776193 – 2013-03-26T03:09:23.193

for f in 'svn ls repo_path'; path/${f}trunk/path; done
Comes out as: path/var/%0Dtrunk/path
(f is "var/" not "var", so path/$f/trunk/path would not work)

You were right about both things. The for loop works perfectly now. Thank you so much! You saved me a huge headache! Edit: I will keep that in mind for future superuser etiquette. – user1776193 – 2013-03-26T03:21:53.373
Thanks, I'm glad you reminded me! Should have left it as answered in the first place, since you did answer my question. :) – user1776193 – 2013-03-26T04:03:44.220
