delete rows in a file based on the rows of another file
I need to delete rows based on the number of lines in a different file, I have a piece of code with me working but when I merge with my C application, it doesnt work.
Code:
sed '1,'\"`wc -l < /tmp/fileyyyy`\"'d' /tmp/fileA > /tmp/filexxxx
Can anyone give me an alternate solution for the above

seunshare [ -v ] [ -c ] [ -C ] [ -k ] [ -t tmpdir ] [ -h homedir ] [ -Z context ] -- executable [args]
DESCRIPTION
Run the executable within the specified context, using the alternate home directory and /tmp directory. The seunshare command unshares

execute the application under the specified SELinux context.
-h homedir
Alternate homedir to be used by the application. Homedir must be owned by the user.
-t tmpdir
Use alternate tempory directory to mount on /tmp. tmpdir must be owned by the user.
-c --cgroups
Use cgroups to control this copy of seunshare. Specify parameters in /etc/sysconfig/sandbox. Max memory usage and cpu usage are to
be specified in percent. You can specify which CPUs to use by numbering them 0,1,2... etc.
-C --capabilities
Allow apps executed within the namespace to use capabilities. Default is no capabilities.
-k --kill
Kill all processes with matching MCS level.
-Z context
Use alternate SELinux context while runing the executable.
