If I run the command s3cmd get s3://bucket/file.gz - I get binary output on the screen. If I try to pipe this to gzip with s3cmd get s3://bucket/file.gz - | zcat I get gzip: stdin: not in gzip format.
How can I get zcat to pick it's input from stdin?
I have a script that takes an input with a -i flag. The input file I have is compressed (.gz). What I want to do (not sure it's possible), because the file is huge, do some thing like this:
gunzip -c myfile.gz | myScript.pl -i STDIN -o myoutfile.txt
So pipe the output of the decompression to my scripts input flag.
wc -l | test -eq 1
This doesn't work. I want to compare the result of wc with the value of 1. How can I do that?
This question may sound a bit stupid, but I can not really see the difference between redirection and pipes.
Redirection is used to redirect the stdout/stdin/stderr, e.g. ls > log.txt.
Pipes are used to give the output of a command as input to another command, e.g. ls | grep file.txt.
But why are there two operators for the same thing?
Why not just write ls > grep to pass the output through, isn't this just a kind of redirection also? What I am missing?
At the moment his is what I do:
Step 1:
locate fooBar
/home/abc/fooBar
/home/abc/Music/fooBar
Step 2:
Manually perform a removal, by copy-pasting each line.
rm /home/abc/fooBar
rm /home/abc/Music/fooBar
How do I do this in one step? Something like
locate fooBar > rm
Thanks.
