Script help

Hi!
i making a script to let me read a txt with filepath and can convert the image inside the filepath with imagemagick changing the name and source folder, i test line by line (without while loop) and work fine, but when i run the sh give me this error:
Bad for loop variable

this is the script:

#!/bin/bash
while IFS= read -r line
do
lala=$(echo $line | cut -d "/" -f 5)
caja=$(echo $line | cut -d "/" -f 5)
caja+="_TA_"
cd $line
ls $line | sed 's/ta_/convert ta_/g' > /home/procesadorm.txt
cant=$(wc -l < /home/procesadorm.txt)
rm /home/procesadorr.txt
for ((i=0;i<$cant;i++)); do echo $line >> /home/procesadorr.txt; done
cat /home/procesadorr.txt |

sh /home/procesador.sh
done < "/script/pendiente.txt"

if anyone can helpme i dont know why dont work!
Thx

This code is hard to read and probably not going in a direction you want.

Rather than a wall of code, please, tell us what you are trying to do.
For example (this is a guess):

I am trying to create directories for files named using lines of a file.

Simply giving us dozens of pipes with no explanation will not get you any useful help.

Thanks.

#!/bin/bash
#This is a while looping in the /script/pendiente.txt where there was a list of #filepath, inside has TIF images in all the script will build the sh script who #convert with imagemagick al the tif in the source folder to a jpg with name #changed

Thx to all to help me in this
sorry about my english i really speak spanish

In fact, I've still got no chance to understand what you are doing without samples of the input files. But some comments:

• don't redirect into the file that you use as input; the redirection takes precedence and truncates the input file BEFORE it can be read.
• with a smart regex you can have ALL those sed commands in one single command.
• Why don't you save those sed results in a variable that can be reused later in need be?
• Why do you use sed at all? Use bash 's parameter expansion capabilities on $line .
• Not sure if you really want to call that .sh script for every line in your input file.

i test all lines without loop and work fine, i using files as a input files because i using this to make a sh file, and then run it i can try making only one sh for all the file to convert, but still will need the output file for later make a paste. But the loop error will continue happening
