bash - Editing a variable inside of a script with sed -

perhaps i'm stetching bash bit far, have variable containing list of urls.

#!/bin/bash     /* returns /path/page/one.php /path/subseciton/ /path/to/this/section/ /path/to/yet/aother_section/about.php etc */ list_of_urls = $(pull_urls.sh)  

then have loop running, pulling text content old server , new server. on each of i'm running various diff commands see has changed.

for in $urls              echo $i         storage_area=./working/$i/         mkdir -p $storage_area           xidel http://oldserver/$i  -e '//div[@id="maincontent"]//p' > $storage_area/old.txt         xidel http://newserver/$i -e '//div[@id="content"]//p' > $storage_area/new.txt         diff $storage_area/old.txt $storage_area/new.txt > $storage_area/diff.diff         wdiff $storage_area/old.txt $storage_area/new.txt > $storage_area/wdiff.wdiff     done 

my problem need remove trailing slash. advisable in following way?

// inside loop, before xidel calls i=$(echo $i | sed -e 's/\/$//g') 

how in way:

kent$ i=foo/                                                                                                                                              kent$ i=${i%/}                                                                                                                                            kent$ echo $i foo 

if prefer doing sed, consider use separator other /, since want use slash in pattern:

kent$ i=/path/to/this/section/ kent$ i=$(sed 's#/$##'<<<"$i") kent$ echo $i /path/to/this/section
