Top Forums UNIX for Beginners Questions & Answers Processing files one by one using data from pipe Post 303007112 by Yoda on Saturday 11th of November 2017 09:20:57 PM

One approach is to load names into an indexed array and then use another loop to rename the files using the array:-
Code:
#!/bin/ksh

# Load names into an indexed array
c=1
while read file
do
        A_fname[$c]="$file"
        (( ++c ))
done < names.txt

# Rename *.test files using array value
c=1
for file in *.test
do
        if [ ! -z ${A_fname[$c]} ]
        then
                print "mv ${file} ${file%%-*}-${A_fname[$c]}.test"
                (( ++c ))
        fi
done

Remove the highlighted print and rerun if the output looks good.

NAME
explain_pipe_or_die - create pipe and report errors SYNOPSIS
#include <libexplain/pipe.h> void explain_pipe_or_die(int *pipefd); DESCRIPTION

On failure an explanation will be printed to stderr, obtained from explain_pipe(3), and then the process terminates by calling exit(EXIT_FAILURE). This function is intended to be used in a fashion similar to the following example: explain_pipe_or_die(pipefd); pipefd The pipefd, exactly as to be passed to the pipe(2) system call. Returns: This function only returns on success. On failure, prints an explanation and exits. SEE ALSO
