Top Forums Shell Programming and Scripting For in loop - two input variables Post 303024077 by MadeInGermany on Friday 28th of September 2018 12:33:57 PM

@bakunin, the var// / modifier exists in bash or zsh or ksh93 (and works the same).

But a "wanted output" would clarify things.
I guess you want to delete embedded strings .txt OR .log from the file names.
Unfortunately there is no OR in the variable modifier.
A solution is: one loop for each string. You can consolidate it into a function
Code:
cut_from_fnames(){
  text=$1
  subst=$2
  [ -n "$text" ] || exit
  for i in ./*"$text"*.?*
    do mv "$i" "${i/$text/$subst}"
  done
}

And run the function two times
Code:
cut_from_fnames ".log" "-"
cut_from_fnames ".txt" "-"

Notes:
In general the mv -- is a good idea if $i starts with a -
but in this case not needed because it starts with ./
The (trailing) ? glob requires one (more) character
The var// / variable modifier is greedy, while the var/ / modifier stops at the first match

NAME
nvram - manipulate Open Firmware NVRAM variables SYNOPSIS
nvram [ -p ] [ -f filename ] [ name ] [= value ] ... DESCRIPTION
The nvram command allows manipulation of Open Firmware NVRAM variables. It can be used to get or set a variable. It can also be used to print all of the variables or set a list of variables from a file. Changes to NVRAM variables are only saved by clean restart or shutdown. In principle, name can be any string. In practice, not all strings will be accepted. New World machines can create new variables as desired. Some variables require administrator privilege to get or set. The given value must match the data type required for name. Binary data can be set using the %xx notation, where xx is the hex value of the byte. The type for new variables is always binary data. OPTIONS
-p Print all of the Open Firmware variables. -f filename Set Open Firmware variables from a text file. The file must be a list name=value statements. If the last character of a line is , the value will be continued to the next line. EXAMPLES
example% nvram boot-args="-s rd=*hd:10" Set the boot-args variable to "-s rd=*hd:10". This would specify single user mode with the root device in hard drive partition 10. example% nvram my-variable="String One%00String Two%00%00" Create a new variable, my-variable, containing a list of two C-strings that is terminated by a NUL.
