Dear All,
I will be having the below files in a directory.
FORM_9757_TYUIOP_1.DAT
FORM_9840_OPRTOP_2.DAT
FORM_9757_TIRTOP_3.DAT
So, from the directory, I have to find only those file which have "OP" at the highlighted position. The file name format is fixed.
Please help 
Hello,
the wildcard for a single character is ? , so your ls-command would look like this:
$ touch FORM_9757_TYUIOP_1.DAT FORM_9840_OPRTOP_2.DAT FORM_9757_TIRTOP_3.DAT
$ touch XOPX.DAT
$ touch X.DAT
$ ls
FORM_9757_TIRTOP_3.DAT FORM_9840_OPRTOP_2.DAT XOPX.DAT
FORM_9757_TYUIOP_1.DAT X.DAT
$ ls ??????????????OP??????
FORM_9757_TIRTOP_3.DAT FORM_9757_TYUIOP_1.DAT FORM_9840_OPRTOP_2.DAT
with command find
find pathOfYourFolder -name "*OP*"
Instead of * which matches zero or more of any character, you could use ? to indicate a single character, so:-
ls *Hello*.txt
ls ??????Hello???.txt
The first will match any files that has Hello anywhere in the name and finishes with .txt where the second option will only match files that have Hello from character 7, then any three characters and ending .txt
If your current directory has the following files:-
Hello.txt
Hello-me.txt
123Hello.txt
123456Hello123.txt
.... The first command will match all files, but the second will only match the last file.
You can use this as a file name mask for find too, e.g.
find /your/path -name "??????Hello???.txt"
I hope that this helps,
Robin
You could also use the underscores as markers:
ls *_*_*OP_*.DAT
Although a bit less exact, it will probably get you what you want..
The unquoted glob-expression is evaluated by the shell, so you can as well do
echo ????_????_????OP_?????
ls -1 (or ls if not seeing an interactive terminal) puts output line by line, that is sometimes convenient. Like the following that pipes the output to grep
ls -1 | grep '^...._...._....OP_.....$'
grep uses Regular Expression: . is a single character, ^ is line start, $ is line end.
ls FORM_[0-9][0-9][0-9][0-9]_[A-Z][A-Z][A-Z][A-Z]OP_?.DAT
or
ls FORM_[0-9][0-9][0-9][0-9]_[A-Z][A-Z][A-Z][A-Z]OP_[0-9].DAT
Hello Guys,
Thanks a lot for your help.
However I have a new question now.
My file will be of type
FORM_PTIR_9820_ANFDOP_20150716_00413561.DAT
FORM_PTIR_9820_ANFDOP_20150716_00413561.DAT.SKIP
FORM_PTIR_9820_ANFDOP_20150716_00413561.DAT.ERROR
I have got the answer of how to pick up FORM_PTIR_9820_ANFDOP_20150716_00413561.DAT . But now the problem is DAT can be TXT and there can be lot of files . Like,
FORM_PTIR_9820_ANFDOP_20150716_00413561.DAT
FORM_PTIR_9820_ANFDOP_20150716_00413561.TXT
FORM_PTIR_9820_ANFDOP_20150716_00413562.DAT
FORM_PTIR_9820_ANFDOP_20150716_00413563.DAT
FORM_PTIR_9820_ANFDOP_20150716_00413561.DAT.SKIP
FORM_PTIR_9820_ANFDOP_20150716_00413561.DAT.ERROR
So,
I cannot use ????_????_????_????OP_*.??? to transfer all files with OP in middle and ending with .DAT or .TXT to other folder.
????_????_????_????OP_*.???* will pick up .ERROR and .SKIP files as well, so how do I skip the .ERROR and .SKIP files and transfer rest to other folder ?
Please help
I don't understand.
$ ls -1
FORM_PTIR_9820_ANFDOP_20150716_00413561.DAT
FORM_PTIR_9820_ANFDOP_20150716_00413561.TXT
FORM_PTIR_9820_ANFDOP_20150716_00413562.DAT
FORM_PTIR_9820_ANFDOP_20150716_00413563.DAT
FORM_PTIR_9820_ANFDOP_20150716_00413561.DAT.SKIP
FORM_PTIR_9820_ANFDOP_20150716_00413561.DAT.ERROR
$ ls -1 ????_????_????_????OP_*.???
FORM_PTIR_9820_ANFDOP_20150716_00413561.DAT
FORM_PTIR_9820_ANFDOP_20150716_00413561.TXT
FORM_PTIR_9820_ANFDOP_20150716_00413562.DAT
FORM_PTIR_9820_ANFDOP_20150716_00413563.DAT
Aren't these the expected ones?
If yes you can copy/move them to other folder:
cp ????_????_????_????OP_*.??? /other/folder/
Dear Friends,
Thanks. maybe my previous post was not up to the mark to explain what is required.
My current directory is like, below
----------------------------
FORM_PTIR_9820_ANFDOP_20150716_00413562.DAT_bkp
FORM_PTIR_9820_ANFDOP_20150716_00413563.DAT_bkp
FORM_PTIR_9820_ANFDEX_20150716_00413562.DAT
FORM_PTIR_9820_ANFDEX_20150716_00413563.DAT
FORM_PTIR_9820_ANFDOP_20150716_00413561.DAT
-------------------------------
Now with ????_????_????_????OP*.??? I will get one file (the last one in above list). How to get a negation of that ? I mean how to list all other files except for these ones which have been derived using the mentioned wildcard ? Please help I tried -I, did not work.
something like
ls *|grep -v "$(ls ????_????_????_????OP_*.???)"
but this is getting ridiculous, why not say exactly what you want : All the requisites and give ALL the information?
Thanks buddy ! Honestly I know this is getting messy. I would let you know as soon as I have the complete info. Till now, I have asked what I knew of.

=====================================
now I have to move the files which are excluded from the wildcard ????_????_????OP*.??? to a folder called NOTProcessed.
list will give me a set of files which I will have to write in a txt file and then move them one by one.
How can we achieve move with this ?
Say,
ls -ltr | grep -v ????_????_????_????OP*.??? | grep -v ^d
gives me set of all files excluding directory (in any). Now I want to move these files(result set from ls command) to folder NOTProcessed. How can we achieve this ? I want to avoid file names to be written in a txt file and then loop over these names and put one by one. Can we move this in a single command ? Kindly help ! I need it badly...
Try this one
for i in *
do
if [[ -f "$i" ]] && [[ "$i" != ????_????_????_????OP_*.??? ]]
then
echo mv "$i" NOTProcessed/
fi
done
Instead of * you can use e.g. FORM* do reduce the scope.
Remove the echo to activate.
With a recent bash , for a selection inversion, try
shopt -s extglob
ls !(????_????_????_????OP*.???)
