Hi Everyone!
I would like ask if there's a better way I can delete multiple lines in a file1 by collecting all criteria from file2.
file1:
a
b
c
d
e
f
file2:
a
e
f
The expected value will be:
b
c
d
The code below seems to work however if is taking much time when dealing with huge records.
Hi all,
This is what I did:
Code:
ftp> ls > filelist.txt
ftp> output to local-file: filelist.txt? y
200 PORT command successful
150 Opening ASCII mode data connection for file list
450 >: No such file or directory
ftp>
(emphasis mine to highlight user input)
This creates a local file filelist.txt but its empty.
Thanks for reading.
Hi,
I have a filelist named filestomove.txt.
It can contain any number of files that need to be moved to a subdirectory.
All the files from filelist are in the same directory as the filelist, let say it's called Folder1.
All the files need to be moved to subfolder Folder1/Subfolder1.
Thanks!

I have very limited coding skills but I'm wondering if someone could help me with this. There are many threads about matching strings in two files, but I have no idea how to add a column from one file to another based on a matching string.
I'm looking to match column1 in file1 to the number following the string "Gene_" in file2.
Hi,
I have multiple files in a directory. Each file will have a header.I have to check if any of the files has 0 rows other than the header then I have to delete the files.
Here Empty file in my case means a file has header information but no data.
I'm quite new to Linux and specially to the shell and all of its commands. My goal is to move some files in every directory to another directory. To be more clear, I have this:
/DIR
- /dir1
- file1
- file2
- ...
- /dir2
- file1
- file2
- ...
- ...
- /dirn
- file1
- file2
- ...
I don't quite understand how the computer reads this command.
cat file1 file2 1> file.txt 2>&1
If I understand, 2>&1 simply redirect Standard Error to Standard Output.
By that logic, the command reads to me as follows:
concatenate files file1 and file2.
send stdout from this operation to file.txt.
send stderr to stdout.
end?
I'm not sure what the computer's doing.
I have two files,
file1.txt:
1 abc
2 def
2 dgh
3 ijk
4 lmn
file2.txt
1 opq
2 rst
3 uvw
My desired output is:
1 abc opq
2 def rst
2 dgh rst
3 ijk uvw
I have tried using the 'join' command (ie. 'join file1.txt file2.txt') but it returns the error that file1.txt is not sorted because of the repeated value (ie. 2).
Does anyone know how to solve this? Thanks!
