Thread: Rename SAC Files

Hello Massita,
Here's an example shell + SAC program that uses saclst utility to rename
files. You may adapt this to your needs.

#!/bin/sh

# rename rdseed/mseed output .SAC files to standard name
# yyyy.jday.hh.min.sec.stnm.channel.sac
# Modify data_dir as needed.
# Created On: 19 Feb 2015

echo 'Enter wildcard [e.g. *.SAC, *__SAC]:'
read wcard

cur_dir=`pwd`
data_dir='my_computer/data_directory'

cd $data_dir

sacfiles=`ls $wcard`

for sacfile in $sacfiles
do
date=`saclst KZDATE f $sacfile | awk '{print $2}'`
yy=`echo "$date" | awk -F"/" '{print $1}'`

jd=`saclst NZJDAY f $sacfile | awk '{print $2}'`

time=`saclst KZTIME f $sacfile | awk '{print $2}'`
hh=`echo "$time" | awk -F":" '{print $1}'`
min=`echo "$time" | awk -F":" '{print $2}'`
sec=`echo "$time" | awk -F":" '{print $3}'`

stnm=`saclst KSTNM f $sacfile | awk '{print $2}'`
cmpnt=`saclst KCMPNM f $sacfile | awk '{print $2}'`

new_name="$yy.$jd.$hh.$min.$sec.$stnm.$cmpnt.SAC"

echo "OLD NAME: $sacfile"
echo "NEW NAME: $new_name"

# Files are renamed here
echo "$sacfile" | awk -v name=$new_name '{print "mv "$1" "name" "}' | sh
done

cd $cur_dir
