I have hundreds of sub-directories which contain a dollar sign (i.e., "$") as the 1st character in their names, each of which needs to be visited. These sub-directories can not be renamed. The bash script function tries to visit each and (so far) to echo the path its in. Trying to do this via a built path string then eval it.

The line that print "cmd=${cmd}" indeed shows "cmd=cd /rbyoko/c/$Ono.RCB" as expected - however, the eval command mis-interprets the $Ono.RCB (probably as $Ono being empty var) and results in: "-bash: cd: /rbyoko/c/.BIN/: No such file or directory" then the following line prints "We are in /home/user" (where the script was run from).

My question: how do I eval the string (and/or escape the sub-directory with "$") to actually succeed in visiting the desired sub-directory?

Here is my function:

visit_tree_recbin() { strings="cdhlotpw" MACHINE=`uname -a` PWD=`pwd` for i in $(seq 1 ${#strings}) do c="${strings:i-1:1}" echo "Letter $i: $c" #build eval string to do: cd "/rbyoko/${c}/\$Ono.RCB/" x1="cd /rbyoko/${c}/" x2="\$" x3="Ono.RCB/" cmd="${x1}${x2}${x3}" echo "cmd=${cmd}" eval "${x1}${x2}${x3}" echo "We are in " `pwd` done }
