Compressing the core files during core generation

Question

Is there way to compress the core files during core dump generation?

If the storage space is limited in the system, is there a way of conserving it in case of need for c

Answer 1

For an embedded Linux systems, following script change perfectly works to generate compressed core files in 2 steps

step 1: create a script

touch /bin/gen_compress_core.sh
chmod +x /bin/gen_compress_core.sh

cat > /bin/gen_compress_core.sh #!/bin/sh exec /bin/gzip -f - >"/var/core/core-$1.$2.gz"
ctrl +d

step 2: update the core pattern file

cat > /proc/sys/kernel/core_pattern |/nuova/bin/gen_compress_core.sh %e %p ctrl+d
