Put file names into text

Question

I have at least 40 files (20 in xml. format and 20 in safe. format). As example some of this:

iw1-20150612.SAFE.safe
iw2-20150714.SAFE.safe
iw1-20150612.xml
iw2-20150714.xml

I want to put this file names in a txt file in a certain place of text via terminal in Linux (or text is added during this process)

The text can be any as example:

anytext iw1-20150612.SAFE.safe
anytext2 iw1-20150612.xml anytext2  iw1-20150612.xml
anytext Iw2-20150714.SAFE.safe
anytext2 iw2-20150714.xml anytext2  iw2-20150714.xml

Example that I need here:

awk 'NR>1 {print $0}' < ../og/iw1-20150612.SAFE.safe > tmp_file
cat ../og/iw1-20150612.xml tmp_file ../og/m.xml > ./iw1-20150612.xml
awk 'NR>1 {print $0}' < ../og/iw2-20150714.SAFE.safe > tmp_file
cat ../og/iw2-20150714.xml tmp_file ../og/m.xml > ./iw2-20150714.xml
#and etc 

It's also important to keep sorting by file name as in the folder. My attempt:

find /any/directory/ -type f -printf "%f\n" >> data.txt

But I don't know how to 'choose a place' to insert text.

Answer 1

You can use a simple bash for loop to loop over the filenames. As long as each safe file has a corresponding xml file, you can

• loop over the safe files,
• get the base filename without extension
• and create the xml filename and the texts from there

script.sh

#!/bin/bash

OUTFILE=textfile
EXTENSION=.SAFE.safe

# rm -rf "$OUTFILE" # uncomment if required
for f in *${EXTENSION}
do
    # f i a .. safe file we remove the extension 
    base=${f%%$EXTENSION}
    echo -e "anytext $f\nanytext2 ${base}.xml anytext2 ${base}.xml" >> "$OUTFILE"
done

Set OUTFILE as required, uncomment the rm if required.

Update using awk

If you have many files and the bash for loop is to slow due to frequent writes to $OUTFILE, here is a more shell-style version of the same idea:

• we pipe the SAVE.safe filenames into awk,
• use the dot as field separator (thus $1 is the basename, $0 the original filename)

• and create the desired text with printf:

  ls -1 *.SAFE.safe | awk -F. '{printf("anytext %s\nanytext2 %s.xml anytext2\n",$0,$1)}'
