Top Forums UNIX for Beginners Questions & Answers Renaming the file names in a directory Post 302996158 by Corona688 on Thursday 20th of April 2017 11:45:01 AM

With 15 posts under your belt, you should have figured out code tags by now. Select text and hit the code button, the Image button.

`ls *.txt` is redundant, for file in *.txt does the same thing more reliably since it will not be confused by spaces in filenames.

If I understand you I think this may work:

Code:
#!/bin/bash

# IFS is a special variable which controls splitting.
# Set it to _ and we can split on that string.
# But we will need to restore its original value later!
OLDIFS="$IFS"
IFS="_"

for file in *.txt
do
  echo 'The file name is ......' $file

  # Split on IFS and store in $1, $2, $3 variables.
  # $1="i", $2="can", $3="phone", $4="170420.txt"
  set -- $file 
  shift 3 # Remove "i", "can", "phone", leaving $1="170420.txt"

  new_file=$(printf "_%s" "$@") # new_file=_$1_$2_$3_...
  new_file="${new_file:1}" # Strip off leading _

  echo "The new file name is ...... $new_file"
  echo mv ${file} $new_file
done;

IFS="$OLDIFS"

Remove the echo from mv once you've tested and are sure this does what you want.

NAME
paps - UTF-8 to PostScript converter using Pango SYNOPSIS
paps [options] files... DESCRIPTION
paps reads a UTF-8 encoded file and generates a PostScript language rendering of the file. The rendering is done by creating outline curves through the pango ft2 backend. OPTIONS
These programs follow the usual GNU command line syntax, with long options starting with two dashes (`-'). A summary of options is included below. --landscape Landscape output. Default is portrait. --columns=cl Number of columns output. Default is 1. Please notice this option isn't related to the terminal length as in a "80 culums terminal". --font=desc Set the font description. Default is Monospace 12. --rtl Do right to left (RTL) layout. --paper ps Choose paper size. Known paper sizes are legal, letter and A4. Default is A4. Postscript points Each postscript point equals to 1/72 of an inch. 36 points are 1/2 of an inch. --bottom-margin=bm Set bottom margin. Default is 36 postscript points. --top-margin=tm Set top margin. Default is 36 postscript points. --left-margin=lm Set left margin. Default is 36 postscript points. --right-margin=rm Set right margin. Default is 36 postscript points. --gutter-width=gw Set gutter width. Default is 40 postscript points. --help Show summary of options. --header Draw page header for each page. --markup Interpret the text as pango markup. --lpi Set the lines per inch. This determines the line spacing. --cpi Set the characters per inch. This is an alternative method of specifying the font size. --stretch-chars Indicates that characters should be stretched in the y-direction to fill up their vertical space. This is similar to the texttops behaviour. AUTHOR
