Hi,

Try it:

***************
#!/bin/bash

file=$1
saclst evlo evla f $file
awk -v p=$file '{printf "r "p"\nch evlo %f evla %f\nwh\nq\n",$1,$2}' coord.txt | sac
saclst evlo evla f $file

Hi ,

The above command helps but I would like to pass the file name from the command prompt. However this code is not reading the files. $1 is the filename. The awk command cannot read the file.
#!/bin/bash
file="$1"
saclst evlo evla f "$file"
awk '{printf "r "$file"\nch evlo %f evla %f\nwh\nq\n",$1,$2}' coord.txt | sac
saclst evlo evla f "$file"

Thanks,

Hello,

I would like to modify the EVLA and EVLO values in the header using bash script. The lat and long values are stored in coord.txt file. I used the following script but not sure why it is not reading from the file. The coord file contains two values column 1 lat and column 2 long.

#bin/bash!
saclst evlo evla f|awk '{a+=$1} {b+=$2} {printf "r NET.STA1216..BXE.sac\nch %f %f \nwh\nq\n",a,b} END{print "quit"}' | sac coord.txt

However this command works.
printf "r NET.STA1216..BXE.sac\nch evlo 100 evla 100 \nwh\nq\n" | sac

Thanks,
Tannistha
