Full Discussion: Should i delete core files ?
Should i delete core files ?

Good morning, i need your help please

By searching some of the largest files i found some core files that take up much space

This is the command:
find ./ -type f -name core -exec file {} \;

./xptol/tel/tasacion/CIERR/exe/core:    ELF 64-bit MSB core file SPARCV9 Version 1, from 'batch_borrar'
./xptol/tel/tasacion/CIERR/PARCIAL/core:        ELF 64-bit MSB core file SPARCV9 Version 1, from 'batch_borrar'
./xptol/tel/tasacion/RECEP/core:        ELF 32-bit MSB core file SPARC Version 1, from 'sleep'
./xptol/shell/core:     ELF 64-bit MSB core file SPARCV9 Version 1, from 'sqlplus'

and some of then are larger

roduccion/explotacion # ls -lrth ./xptol/tel/tasacion/CIERR/exe/core 
-rw-------   1 xptol    explotacion     14G Sep 22  2017 ./xptol/tel/tasacion/CIERR/exe/core
/produccion/explotacion # 
/produccion/explotacion # ls -lrth ./xptol/tel/tasacion/CIERR/PARCIAL/core
-rw-------   1 xptol    explotacion    2.4G Sep 20  2008 ./xptol/tel/tasacion/CIERR/PARCIAL/core

I wonder if i can remove these files without affecting any application or the operating system itself?

Thanks for your help in advanced

gcore - get core images of running processes SYNOPSIS
gcore [-pgF] [-o filename] [-c content] process-id... DESCRIPTION
The gcore utility creates a core image of each specified process. By default, the name of the core image file for the process whose process ID is process-id will be core.process-id. OPTIONS
The following options are supported: -c content Produces core image files with the specified content. The content description uses the same tokens as in coreadm(1M). The -c option does not apply to cores produced due to the -p or -g flags. -F Force. Grabs the target process even if another process has control. -g Produces core image files in the global core file repository with the global content as configured by coreadm(1M). The com- mand will fail if the user does not have permissions to the global core file repository. -o filename Substitutes filename in place of core as the first part of the name of the core image files. filename can contain the same tokens to be expanded as the paths in coreadm(1M). -p Produces a core image file in the process-specific location with the process-specific content for each process as config- ured by coreadm(1M). The command will fail if the user does not have permissions to the per-process core file repository. OPERANDS
The following operand is supported: process-id process ID EXIT STATUS
The following exit values are returned: 0 On success. non-zero On failure, such as non-existent process ID. FILES
core.process-id core images ATTRIBUTES
