You're only renaming directories, so the -type d option for find is a boon. Also, if you really have "hundreds of directories," it's just possible that there are so many that glob to "*abc*' that the shell can't handle the command line. When this is true, I try to use something like this untested code:
(Thanks to oombera for the `dirname "$dn"` bit. Somehow I keep forgetting about that ...)
Part of your problem might be filenames that contain spaces --- common on "modern" Windows boxes and not unheard of on Unices --- so I put in an extra statement and some more quotes. If this is guaranteed not to be part of your problem, all the "double quotes" can come out.
You should also really carefully consider the other posters' cautions about duplicate file names, too.
Hi,
This is what I would like to do.
1. Find all directories named "ByHost" in a specified directory
2. Rename all .plist files inside "ByHost" directories
This is the way I have been able to do it so far.

Hi,
I'm not very experienced in shell scripting and that's probably why I came across the following problem:
I do have several hundred pairs of text files (PF00x.spl and PF00x.shd) where the first file (PF00x.spl) needs to be renamed according a string that is included in the second file... (12 Replies)
Hello guys,
I was looking for a shell script that removes all the special characters from the files and the subdirectories recursively. I could not locate it any more. Dose any body have a similar script that dose that?
Thanks for the help.

I can rename a file with sequential numbers from 1 to N with this script:
num=1
for file in *.dat;do
mv "$file" "$(printf "%u" $num).txt"
let num=num+1
done
The script begins with renaming a some.dat file to 1.dat.txt and goes on sequentially renaming other DAT files to... (1 Reply)

subst
subst(1T) Tcl Built-In Commands subst(1T)__________________________________________________________________________________________________________________________________________________NAME
subst - Perform backslash, command, and variable substitutions
SYNOPSIS
subst ?-nobackslashes? ?-nocommands? ?-novariables? string
_________________________________________________________________DESCRIPTION
This command performs variable substitutions, command substitutions, and backslash substitutions on its string argument and returns the
fully-substituted result. The substitutions are performed in exactly the same way as for Tcl commands. As a result, the string argument
is actually substituted twice, once by the Tcl parser in the usual fashion for Tcl commands, and again by the subst command.
If any of the -nobackslashes, -nocommands, or -novariables are specified, then the corresponding substitutions are not performed. For
example, if -nocommands is specified, command substitution is not performed: open and close brackets are treated as ordinary characters
with no special interpretation.
Note that the substitution of one kind can include substitution of other kinds. For example, even when the -novariables option is speci- |
fied, command substitution is performed without restriction. This means that any variable substitution necessary to complete the command |
substitution will still take place. Likewise, any command substitution necessary to complete a variable substitution will take place, even |
when -nocommands is specified. See the EXAMPLES below. |
If an error occurs during substitution, then subst will return that error. If a break exception occurs during command or variable substi- |
tution, the result of the whole substitution will be the string (as substituted) up to the start of the substitution that raised the excep- |
tion. If a continue exception occurs during the evaluation of a command or variable substitution, an empty string will be substituted for |
that entire command or variable substitution (as long as it is well-formed Tcl.) If a return exception occurs, or any other return code is |
returned during command or variable substitution, then the returned value is substituted for that substitution. See the EXAMPLES below. |
In this way, all exceptional return codes are ``caught'' by subst. The subst command itself will either return an error, or will complete |
successfully.
EXAMPLES
When it performs its substitutions, subst does not give any special treatment to double quotes or curly braces (except within command sub-
stitutions) so the script
set a 44
subst {xyz {$a}}
returns ``xyz {44}'', not ``xyz {$a}'' and the script |
set a "p} q {r" |
subst {xyz {$a}} |
return ``xyz {p} q {r}'', not ``xyz {p} q {r}''. |
When command substitution is performed, it includes any variable substitution necessary to evaluate the script. |
set a 44 |
subst -novariables {$a [format $a]} |
returns ``$a 44'', not ``$a $a''. Similarly, when variable substitution is performed, it includes any command substitution necessary to |
retrieve the value of the variable. |
proc b {} {return c} |
array set a {c c [b] tricky} |
subst -nocommands {[b] $a([b])} |
returns ``[b] c'', not ``[b] tricky''. |
The continue and break exceptions allow command substitutions to prevent substitution of the rest of the command substitution and the rest |
of string respectively, giving script authors more options when processing text using subst. For example, the script |
subst {abc,[break],def} |
returns ``abc,'', not ``abc,,def'' and the script |
subst {abc,[continue;expr 1+2],def} |
returns ``abc,,def'', not ``abc,3,def''. |
Other exceptional return codes substitute the returned value |
subst {abc,[return foo;expr 1+2],def} |
returns ``abc,foo,def'', not ``abc,3,def'' and |
subst {abc,[return -code 10 foo;expr 1+2],def} |
also returns ``abc,foo,def'', not ``abc,3,def''.
