I have to install multiple packages using shell script and rpm (package) name is in the input file.

I have done it in this below way.

My input file is path is = /mstr/mstr_input_file.txt

MY Script is:

But instead using sleep command i need to keep condition when one package got installed it should start for another to install.

My input file contains:

packagelist=mailx,nc,expect,nfs-utils,telnet,glibc,libX11,libxcb,libXcomposite,libXcursor,libXdamage,libXext,libXfixes,libXi,libXrender,libXtst,glib2,nss,nss-util,nspr,cups-libs,dbus-libs,expat,libXScrnSaver,libXrandr,alsa-lib,cairo,at-spi2-atk,gtk3,gdk-pixbuf2,ibgcc,atk,at-spi2-atk,at-spi2-core,GConf2,libXScrnSaver,libxkbcommon,libwayland-client,libwayland-cursor,gtk3,gdk-pixbuf2 

I dont have a rpm based system in front of me to test that out but assuming your list is called rpmlist.txt and you want to install it with rpm and not yum.

First do:

for i in `cat rpmlist.txt | tr ',' 'n'`; do echo $i ; done

if the output shows a the packages now line by line it should work with:

for i in `cat rpmlist.txt | tr ',' 'n'`; do rpm -i $i ; done

Note: you could replace rpm -i with yum -y (the -y makes shure, you dont have to agree to install the packages it just install them without asking.)

You can use:

yum install $(awk -F ',' 'BEGIN {ORS=" "} {for(i=1;i<=NF;i++) {print $i}}' filename)

awk command will give packages names separated by space as input to yum.

You could use xargs to feed comma separated values to a command:

xargs -d',' yum install < inputfile.csv

If you want to install the packages one by one, you could pass the -n 1 flag to xargs:

xargs -n1 -d',' yum install < inputfile.csv

• 
  < sends the input file to xargs


• 
  xargs -d',' takes ',' as delimiter to generate a list of arguments from the input file to pass them to yum.

You can find and split the lines starting with packagelist with awk:

</mstr/mstr_input_file.txt awk -F'=' '/packagelist=/{print $2}' | xargs -n1 -d',' yum install
