Unzip the Files
I have a list of zip files and regular files in a folder

Code:
/home/data/

Example:
PMExtra_A123_ABC_121001020000.zip
PMExtra_B596_GRT_121001020000.zip
PMExtra_C156_SFD_121001020000.zip
PMExtra_S243_KDF_121001020000.xml
PMExtra_L234_IDF_121001020000.xml

I have to unzip all the .zip files and load into the same folder and remove the .zip files.

.zip files will have the xml files. If the xml file is huge then they zip it. So, how can I unzip all the zip files at a time?

Actually, all the files will be available on a ftp server and since I thought it is hard to put everything in FTP command I thought to put all the files in a local directory and then unzip them.

Have you tried unzip *.zip?

----------------------
Ignore this post. This only works if there is only one .zip file in the current directory.

Hi.

The command gunzip can unpack lists of zip files provided they contain only one file:
Code:
#!/usr/bin/env bash

# @(#) s1	Demonstrate comparison between unzip and gunzip.

# Utility functions: print-as-echo, print-line-with-visual-space, debug.
# export PATH="/usr/local/bin:/usr/bin:/bin"
pe() { for _i;do printf "%s" "$_i";done; printf "\n"; }
pl() { pe;pe "-----" ;pe "$*"; }
edges() { local _f _n _l;: ${1?"edges: need file"}; _f=$1;_l=$(wc -l $_f);
  head -${_n:=3} $_f ; pe "--- ( $_l: lines total )" ; tail -$_n $_f ; }
db() { ( printf " db, ";for _i;do printf "%s" "$_i";done;printf "\n" ) >&2 ; }
db() { : ; }
C=$HOME/bin/context && [ -f $C ] && $C unzip gunzip

pl " Create zipped files:"
./create

pl " Attempt to unzip more than one x.zip with unzip:"
unzip *.zip
ls -lgG t*

pl " Create zipped files:"
./create

pl " Attempt to unzip more than one x.zip with gunzip:"
gunzip -S .zip t*.zip
ls -lgG t*

exit 0

Sorry about that. I should have said: Try:
Code:
for i in *.zip
do      if unzip $i
        then rm $i
        fi
done

Hey thanks!

I found another command online and this works excellent Smilie

Code:
find /home/data/ -name 'PMExtra*.zip' -exec unzip -d /home/data/ {} \;

Using rm command later to remove the zip files.

find is recursive, so this will not work right if you've got multiple folders of zip files, but for the situation you've given it ought to work yes. Smilie

I am really dummy at unix so I really go with single line commands. I use this commands in the IBM ETL tool.

I do not know how to use
Code:
for i in *.zip
do      if unzip $i
        then rm $i
        fi
done

is i the file name?
like

for filename in filepath ? I have to define the variables right?
