virtualenvwrapper.sh

 # path might contain stuff to expand.
 # (it might be possible to do this in shell, but I don't know a
 # cross-shell-safe way of doing it -wolever)
-if echo "$WORKON_HOME" | egrep -e "([$~]|//)" >/dev/null
+if echo "$WORKON_HOME" | egrep -e "([$\~]|//)" >/dev/null
 then
     # This will normalize the path by:
     # - Removing extra slashes (e.g., when TMPDIR ends in a slash)
Tip: Filter by directory path e.g. /media app.js to search for public/media/app.js.
Tip: Use camelCasing e.g. ProjME to search for ProjectModifiedEvent.java.
Tip: Filter by extension type e.g. /repo .js to search for all .js files in the /repo directory.
Tip: Separate your search with spaces e.g. /ssh pom.xml to search for src/ssh/pom.xml.
Tip: Use ↑ and ↓ arrow keys to navigate and return to view the file.
Tip: You can also navigate files with Ctrl+j (next) and Ctrl+k (previous) and view the file with Ctrl+o.
Tip: You can also navigate files with Alt+j (next) and Alt+k (previous) and view the file with Alt+o.
